| rmstar | hi guys. not sure if this is the right place for this question... | 00:11 |
| rmstar | i created a flavor with ephemeral disk space. How do i access this ephemeral drive from the guest OS? I did fdisk, but don't see a new disk. | 00:11 |
| rmstar | i am lanching the instance using heat | 00:11 |

| *** salv-orlando has joined #openstack-nova | 00:27 | |
| stewie925 | :) so it was my fat bulky local.conf that was the culprit lol | 00:27 |
| stewie925 | btw when i tried to run 'neutron net-list' i am getting "public endpoint for network service in RegionOne region not found" | 00:28 |
| stewie925 | how do you check your network list? | 00:28 |
| *** sorrison_laptop has quit IRC | 00:28 | |
| melwitt | by default (for now) devstack sets up nova-network, not neutron. so to list networks with nova-network you have to do 'nova network-list' | 00:29 |
| stewie925 | ahhh thank you!! | 00:29 |
| melwitt | in the future neutron will be the default in devstack, but it isn't yet | 00:29 |
| stewie925 | well yes it works, but its empty hehe | 00:30 |
| *** salv-orlando has quit IRC | 00:30 | |
| melwitt | oh, well, that's a complicated reason why, but it's because cells v1 | 00:30 |
| melwitt | if you go into mysql and show databases, you'll see a few. one of them is for the parent, one for the child | 00:31 |
| *** jamielennox|away is now known as jamielennox | 00:31 | |
| stewie925 | ahhh - I've learned so much this week thanks o you | 00:31 |
| melwitt | networks are in the child database, which is not accessible by the nova-api | 00:31 |
| melwitt | there are a lot of limitations and things that don't work in cells v1 because not all data is synced back and forth between parent and child | 00:32 |
| stewie925 | thanks to you, I mean :) | 00:32 |
| stewie925 | oh I see, melwitt | 00:32 |
| melwitt | which is why we're working on cells v2 which will not have those problems | 00:32 |
| melwitt | you can see the network in the child cell if you do 'nova-manage --config /etc/nova/nova-cells.conf network list' I think | 00:33 |
| melwitt | that will make nova-manage point at the child cell db | 00:33 |
| melwitt | and read directly from it | 00:33 |
| stewie925 | oh I could try that | 00:34 |
| melwitt | but usually when I want to look around I just 'mysql -u root -p' and 'show databases' and go into each one and look in the different tables | 00:34 |
| melwitt | you can see by doing that are things are separated in cells v1 | 00:34 |
| melwitt | *how things are separated | 00:34 |

| stewie925 | thanks for sharing, melwitt - and your inifinite patience with me :) | 00:37 |
| stewie925 | btw yeah the nova-manage command you shared did work | 00:37 |
| stewie925 | am just about 1.5 months into openstack open source here | 00:38 |

| auggy | stewie925: we currently have a documentation project to clean up the API docs in nova and we're always looking for help with the bugs team to help manage our bug queue | 00:47 |
| auggy | stewie925: both are pretty good ways to learn more about contributing to nova, so if you're ever interested, feel free to ask :) | 00:48 |
| stewie925 | hi auggy thank you! definitely will keep that in mind - oh yes you'll have to put up with my questions (kidding) | 00:48 |
| auggy | stewie925: i just started working on Nova last October and i still ask all kinds of questions | 00:49 |
| stewie925 | wow | 00:49 |
| auggy | stewie925: in fact, many people who have worked on this project for a few years still ask questions :) | 00:49 |
| stewie925 | but I gather that openstack beginners have to concentrate on 'one' project | 00:49 |
| auggy | yeah you kind of just dive into something and learn it as best as you can | 00:50 |
| *** amotoki has quit IRC | 00:50 | |
| stewie925 | cause right now I have worked on low-hanging-fruits from trove, puppet, and now trying to work on a nova bug #1533380 | 00:50 |
| openstack | bug 1533380 in OpenStack Compute (nova) "Creating multiple instances with a single request when using cells creates wrong instance names" [Low,Triaged] https://launchpad.net/bugs/1533380 - Assigned to STEW TY (stewie925) | 00:50 |
| stewie925 | lol | 00:50 |
| auggy | wow ambitious :) i started working in infra and moved over to nova, but haven't done much with any of the other projects | 00:51 |
| *** hoangcx has joined #openstack-nova | 00:52 | |
| stewie925 | well, theyre low-hanging fruits haha - but I like your approach (concentrating on one - aka nova) | 00:53 |
| auggy | i'm not sure about other projects but it's a known issue in nova that bugs tagged "low-hanging-fruit" aren't always good for new folks | 00:54 |
| auggy | still it's cool you picked one up and are working on it, best way to learn :) | 00:54 |
| auggy | that's how i've been learning too, i help with the bug skimming and when there's something that looks like i know enough to work on it i pick it up | 00:55 |

| auggy | thanks for helping out stewie925 and don't feel bad about asking questions :) | 00:56 |
| stewie925 | and I believe you have to be proficient in python too, right? | 00:56 |
| auggy | "proficient" haha | 00:56 |
| auggy | i hadn't worked much with python when i started and there's a lot about the language i'm still learning | 00:57 |
| *** jwcroppe has quit IRC | 00:57 | |
| stewie925 | python had me at *arg, **kwarg | 00:57 |
| rmstar | just fyi, i manage to mount the ephemeral. This drive can only be mounted as /dev/sdb. I didn't see this before, because my cinder volume was /dev/sdb. | 00:57 |

| *** gjayavelu has joined #openstack-nova | 08:49 | |
| PaulMurray | bauwser, you've been in discussions about what goes in nova_api vs nova db haven't you? | 08:49 |
| bauwser | PaulMurray: sort of, a bit lagged due to my check-dest bp, but I can help | 08:50 |
| johnthetubaguy | markus_z: I was talking with sfinucan and some others yesterday, there were a few ideas that came up around the config options stuff, I think the ideas are going to get sent to the ML | 08:50 |
| PaulMurray | I'm going to add console auth records to the db | 08:50 |
| PaulMurray | wondering whih one | 08:50 |
| johnthetubaguy | markus_z: would be good to check out those ideas with you, if you have a good moment later | 08:50 |
| PaulMurray | I'm guessing the api, but not sure if there is some guidence somewhere | 08:51 |
| markus_z | johnthetubaguy: yep, no meetings all day long :) | 08:51 |
| johnthetubaguy | PaulMurray: I try to stick to, anything around the instance, lives next to the instance, in the child cell | 08:51 |
| johnthetubaguy | markus_z: lucky person, actually today isn't too bad for me either :D | 08:51 |
| markus_z | johnthetubaguy: wanna discuss it here or on the ML when it's out? | 08:51 |
| johnthetubaguy | markus_z: I am good here, I was thinking about dropping that service list stuff | 08:52 |
| johnthetubaguy | markus_z: I am worried we are getting it wrong, and we will not maintain it properly | 08:52 |
| PaulMurray | johnthetubaguy, ok, I try that - I'm only starting on it so still have to remind myself what I'm doing with it | 08:52 |
| johnthetubaguy | markus_z: I had an idea for an alternative | 08:52 |
| *** shaohe_feng has quit IRC | 08:53 | |
| johnthetubaguy | PaulMurray: the details are a bit tricky though, depends on the usage patterns, like if an API has to aggregate across multiple cells, that not ideal, etc, but console sounds like its not affected | 08:53 |
| johnthetubaguy | markus_z: the alternative is "compute node" or "controller" or both | 08:53 |
| *** shaohe_feng has joined #openstack-nova | 08:53 | |
| markus_z | johnthetubaguy: yeah, I was worried about that too. What's your idea? | 08:53 |
| johnthetubaguy | markus_z: thinking about all the creds (like DB) you should not have on there, its good to tell people about that | 08:53 |
| *** gjayavelu has quit IRC | 08:54 | |
| johnthetubaguy | markus_z: but if we do that, I think we should create two separate sample configs, maybe? | 08:54 |
| johnthetubaguy | we could do some protections to try and stop the compute node reading configs that are not in its sample config file, so we test the split in the gate | 08:55 |
| markus_z | johnthetubaguy: I don't know enough about real life deployments, but if that separation is good enough for most, then I'm good. | 08:55 |
| johnthetubaguy | so its kinda where our security model is going, we are trying to keep sensitive data off the computes, and eventually give them "very limited" trust when connecting to the rest of the system | 08:56 |
| markus_z | johnthetubaguy: So you don't want to put "controller" / "compute" in the help text but show it via two separate files? | 08:56 |
| bauwser | PaulMurray: sorry, missed your point, you asked where to add this console auth records table ? | 08:56 |
| johnthetubaguy | markus_z: while it would be nice if it were machine readable I guess, so the generators can do the right thing, separate sample configs seemed the best I could think of, without introducing something new | 08:57 |
| johnthetubaguy | markus_z: so I could post this to the dev list, and maybe later post to the ops list? | 08:57 |
| bauwser | PaulMurray: the general rule of thumb for the API DB is to keep it with minimal writes | 08:57 |
| bauwser | PaulMurray: for scaling purposes | 08:57 |
| bauwser | PaulMurray: but in general, we want to put things in it if they're cross-cells | 08:57 |
| PaulMurray | bauwser, ok - I'm just getting into this piece of work so I need to get into the details | 08:58 |
| bauwser | PaulMurray: what I'm afraid of a console auth table is that it would have one entry per instance ? | 08:58 |
| markus_z | johnthetubaguy: I'm thinking about the configuration reference manual where it isn't then possible to see the usage (ctrl vs. comp), but that could be a minor thing. | 08:58 |
| bauwser | PaulMurray: if so, putting it in the API DB would be terrible because of the size | 08:58 |
| *** fabian4 has left #openstack-nova | 08:58 | |
| PaulMurray | bauwser, one entry per console authorization | 08:58 |
| markus_z | johnthetubaguy: Yes, let's put it to the ML. | 08:58 |
| johnthetubaguy | markus_z: I think they sometimes do a separate doc for each sample config file | 08:58 |
| PaulMurray | which is generally pretty few | 08:58 |

| bauwser | PaulMurray: my wonders are the relationships you're going to create | 09:00 |
| markus_z | johnthetubaguy: Should be this one: http://docs.openstack.org/mitaka/config-reference/compute/config-options.html | 09:00 |

| johnthetubaguy | sfinucan: I suggested a work breakdown in the ML, let me know if that looks right | 09:46 |
| johnthetubaguy | sfinucan: I included a bit for making the option definition consistent, to track that clean up of list_opts, etc. | 09:47 |
| sfinucan | johnthetubaguy: Yeah, I've got five things: indentation, lists vs individual variables, using 'option.name', lists vs iterators and avoiding deprecated options | 09:47 |
| sfinucan | markus_z: ^^^ they're mostly learnings from our work, afaict. Hopefully you agree :) | 09:48 |

| srushti | sdague: It removes duplicate code and enhances re-usability of code. Similar fix has been merged in cinder https://review.openstack.org/315358 | 10:48 |
| sdague | srushti: not if you leave the adapter layer in there | 10:48 |

| *** tbachman has joined #openstack-nova | 10:49 | |
| tojuvone | Getting late to have new spec and have review, should I put to backlog? | 10:50 |
| PaulMurray | lascii, its easier to explain | 10:51 |
| openstackgerrit | Lucian Petrut proposed openstack/nova: Hyper-V: Implement nova rescue https://review.openstack.org/127159 | 10:51 |
| PaulMurray | lascii, console auth is basically just a server using memcach to store console auth tokens | 10:51 |
| tojuvone | That would be everything I had for maintenance | 10:51 |
| PaulMurray | that are handed out to users when they ask for a vnc console etc. | 10:52 |
| PaulMurray | The user gets a url that connects to the console proxy server, which uses the token in the url to authroise the connection | 10:52 |
| PaulMurray | The problem is that the proxy only has the token to use for lookup | 10:53 |
| PaulMurray | not the instance | 10:53 |
| PaulMurray | Normally it would go to the single console auth server to do the lookup. | 10:53 |
| kashyap | clarkb: When you're about, I found the exact opposite of what you said here: Using `service` and explicit stop+start of libvirt-bin creates the socket file. Using `systemctl` does not succed at all. See all four cases of my testing here: https://kashyapc.fedorapeople.org/behavior-of-systemctl-and-service-with-libvirt-bin-on-Xenial.txt | 10:54 |
| PaulMurray | If we put the data in a database instead of in a memcache server | 10:54 |
| *** apoorv has quit IRC | 10:54 | |
| PaulMurray | we need to be able to look it up using the token | 10:54 |
| lascii | gotcha | 10:54 |
| PaulMurray | so if it goes in the cell db, how do we know which cell ? | 10:54 |
| kashyap | sdague: On your Xenial VM, if you use: `systemctl restart libvirt-bin` do you find the /var/run/libvirt/libvirt-sock created? | 10:54 |
| lascii | so based on that it seems like you'll need to use the api db | 10:54 |
| PaulMurray | which is not ideal | 10:55 |
| lascii | which isn't great. but unless the auth url is changed to include instance info we have no way to find the cell as you point out | 10:55 |
| PaulMurray | because the compute managers generate the data | 10:55 |
| PaulMurray | I did wonder about having a proxy per cell...... | 10:55 |
| PaulMurray | but that's not great either | 10:56 |
| *** shaohe_feng has quit IRC | 10:56 | |
| PaulMurray | (i.e. the url could be used to chose the cell) | 10:56 |
| lascii | I think that would be a decent solution | 10:56 |
| lascii | as you may not want a global proxy for every cell | 10:56 |
| openstackgerrit | Andrey Volkov proposed openstack/nova: Skip instance name templatig in API cell https://review.openstack.org/319091 | 10:56 |
| *** sacharya has joined #openstack-nova | 10:56 | |
| PaulMurray | does expose the difference between cells a little | 10:56 |
| *** shaohe_feng has joined #openstack-nova | 10:56 | |
| lascii | true, but that url should really be opaque to users | 10:57 |
| sdague | kashyap: http://paste.openstack.org/show/497881/ | 10:57 |
| PaulMurray | Actually, it need not be a seperate proxy, could just add something in the resource path | 10:58 |
| lascii | right, that was what I meant earlier about updating the auth_url | 10:58 |
| lascii | my preference would be to keep that data in the cell db, and then route requests there either through an updated resource path or a proxy per cell | 10:59 |
| PaulMurray | lascii, yes, I was thinking about messing with ports etc, but your right, that would do it | 10:59 |
| * kashyap clicks | 11:00 | |
| PaulMurray | we can already set the url on a per host basis - its a config parameter | 11:00 |
| markus_z | sfinucan: I'm a bit torn about moving https://github.com/openstack/nova/blob/d619ad6ba15df1cf7dc92ddf84d1c65af018682f/nova/cmd/dhcpbridge.py#L92 | 11:01 |
| markus_z | sfinucan: It's purely a CLI option and doesn't show in the nova.conf | 11:01 |
| kashyap | sdague: Can you also please tell me: `dpkg -s libvirt-bin | grep Version` | 11:01 |
| PaulMurray | lascii, I'll have to update the spec for this - will you review for me when I do it ? | 11:01 |
| lascii | PaulMurray: okay, so start with a proxy per cell sounds like it would be trivial. then add on url routing later if desired | 11:01 |

| mdbooth | *except* computemanager._handle_bad_volume_detached | 11:02 |
| sfinucan | markus_z: the cli/conf opt divide confuses me, from a centralization perspective :) | 11:02 |
| mdbooth | which contains a comment suggesting that it shouldn't | 11:02 |
| mdbooth | which is weird | 11:02 |
| *** rtheis has joined #openstack-nova | 11:02 | |
| lyarwood_ | mdbooth: it's _detach_volume btw | 11:03 |
| mdbooth | which means that _detach_volume has only a single caller | 11:03 |
| mdbooth | ...right | 11:03 |
| sfinucan | markus_z: We're registering cli opts in Nova conf, but they're not-CLI only as you say | 11:03 |
| lyarwood_ | mdbooth: ah I see sorry | 11:03 |
| mdbooth | _detach_volume has 2 callers, but one of them is apparently never called itself | 11:03 |

| sfinucan | markus_z: Plus they're already pretty "central" in 'nova/cmd' | 11:05 |
| markus_z | sfinucan: I have that tendency as well | 11:05 |
| sfinucan | markus_z: This would change if there were extensive use of register_cli_opt outside of 'nova/conf' and 'nova/cmd', but there isn't | 11:06 |

| frickler | kashyap: I'm missing some context probably, but why do you have that old qemu installed in your sample? default should be 2.5 for xenial | 11:06 |
| kashyap | frickler: I don't know -- whatever `sudo apt-get qemu-kvm` brought in. I normally run libvirt from Git. I'm using this Ubuntu setup to reproduce a bug. | 11:07 |
| sdague | kashyap: Version: 1.3.1-1ubuntu10 | 11:07 |

| *** shaohe_feng has joined #openstack-nova | 11:07 | |
| johnthetubaguy | sfinucan: markus_z: yeah, good points, I quite like saying all reglister_cli_opts should be in nova/cmd near their usage? | 11:07 |
| markus_z | sfinucan: OK, we're on the same page then. Then only https://review.openstack.org/314091 is left for the "move to nova/conf/" part. | 11:07 |
| johnthetubaguy | unless they are shared with conf, I guess | 11:07 |
| lyarwood_ | mdbooth: AFAICT we do end up calling detach_volume in the manager from a normal volume-detach request | 11:08 |
| markus_z | johnthetubaguy: yeah, makes a good general rule | 11:08 |
| kashyap | sdague: Okay, one last test (this will confirm you see sam as Clark's behavior), if you feel like: `sudo service libvirt-bin stop && sudo service libvirt-bin start` | 11:08 |
| mdbooth | lyarwood_: Where's that? | 11:08 |
| sfinucan | markus_z: Yeah, what johnthetubaguy said | 11:08 |
| kashyap | sdague: With the above, do you see a libvirt-sock created too? | 11:08 |
| lyarwood_ | mdbooth: if I'm following the n-api <- rpcapi -> n-cpu flow correctly that is | 11:08 |
| sdague | kashyap: no | 11:09 |
| sdague | but we already came up with a theory for that yesterday | 11:09 |
| sdague | which is why you should be using restart | 11:09 |
| markus_z | sfinucan: You said earlier you wanted to discuss something too? | 11:09 |
| mdbooth | lyarwood_: Which n-api call? | 11:10 |
| kashyap | sdague: I'm trying to compare what I see on my Xenial VM, where using `systemctl` doesn't create the socket. See the summary of the four cases here: https://kashyapc.fedorapeople.org/behavior-of-systemctl-and-service-with-libvirt-bin-on-Xenial.txt | 11:10 |
| lyarwood_ | mdbooth: starting around nova/api/openstack/compute/contrib/volumes.py:413 | 11:10 |
| lyarwood_ | mdbooth: that goes to the compute-api, compute-rpcapi and then the manager | 11:10 |
| lyarwood_ | mdbooth: but again, if I'm reading this right. I'm likely not. | 11:11 |
| sfinucan | markus_z: Yeah. We had a discussion about config opt "best practices" in OSIC standup yesterday. Just a heads up before I send to mailing list, lest you disagree | 11:11 |
| *** Tutj has quit IRC | 11:11 | |
| mdbooth | lyarwood_: Ah, yes. I missed that one. | 11:11 |
| sdague | kashyap: actually, I mispoke, the socket file is there | 11:11 |
| sdague | I was looking in the wrong directory | 11:11 |
| sfinucan | markus_z: We'd five points, that I can recall. | 11:12 |

| *** zzzeek has quit IRC | 11:12 | |
| lyarwood_ | mdbooth: still, that's a valid use case with this change as the instance should be local to the compute that's going to call _driver_detach_volume | 11:12 |
| kashyap | sdague: So, you're saying case (2.b); with `service` stop+start you see the socket file just fine -- correct? | 11:12 |
| sdague | right, but as are all the restart ones | 11:12 |
| mdbooth | lyarwood_: volume delete | 11:12 |
| sdague | where is the devstack patch that moves to restart? | 11:12 |
| sdague | you and clarkb were going to make that one yesterday | 11:13 |
| sfinucan | markus_z: Use lists of opts, rather than variables; don't indent the docstrings; use '[option_group].name' due to duplication bug; use lists rather than iterators; ignore deprecated options | 11:13 |
| lyarwood_ | mdbooth: yeah this is the API remember so that's a detach | 11:13 |
| kashyap | sdague: Haven't done that yet. I was testing locally the current behavior first. Will get to it today. | 11:13 |
| sfinucan | markus_z: there's also a more contention sixth, which was to drop the 'related_options' and 'service which consume this boxes', on account of maintainability. Think John may have covered this already though | 11:14 |
| markus_z | sfinucan: regarding "[option_group].name", that should be solved with https://review.openstack.org/#/c/304802/ | 11:14 |
| sfinucan | s/contention/contentious/ | 11:14 |
| mdbooth | lyarwood_: That's sending the call explicitly to the compute host of the instance | 11:15 |

| sfinucan | markus_z: but that's not released yet, is it? | 11:15 |

| markus_z | sfinucan: dropping the "services" list is something I can agree with. Dropping "related options" would remove a lot of benefit for ops IMO. | 11:16 |
| markus_z | sfinucan: But I don't know yet how to keep that maintained. :/ | 11:18 |
| sfinucan | markus_z: So the primary use case I've identified is an "enable" option, which other dependencies hinge on | 11:19 |
| sfinucan | markus_z: since related options are normally grouped, it might make sense to provide some mechanism for linking a specified opt to an optgroup | 11:20 |
| sfinucan | markus_z: i.e. this option disables this entire group | 11:20 |
| sfinucan | markus_z: the option could even be auto-generated, based on an OptGroup parameter | 11:20 |
| sfinucan | markus_z: *However*, johnthetubaguy pointed out a few other scenarios that wouldn't be covered by this, so it's not a 100% solution | 11:21 |
| mdbooth | lyarwood_: Having 2 methods called 'detach_volume' and 'remove_volume_connection' isn't at all confusing :/ | 11:22 |
| markus_z | sfinucan: Yeah, maybe wait for that decision until we have the help texts about the impact of a single config option to a proper standard. | 11:22 |
| markus_z | sfinucan: I mean, for all options. After that we should have a bigger picture. | 11:22 |

| mdbooth | Is that copied from somewhere? | 11:24 |
| * mdbooth isn't familiar with that | 11:24 | |
| lyarwood_ | yeah from the _driver_detach_volume method | 11:24 |
| openstackgerrit | Sylvain Bauza proposed openstack/nova: Add resource provider tables to the api database https://review.openstack.org/315681 | 11:24 |
| mdbooth | lyarwood_: Got it | 11:24 |
| lyarwood_ | mdbooth: at the top, there's an additional serial_id that's added iirc but isn't required to terminate the connection later on | 11:24 |
| mdbooth | lyarwood_: Hmm, there's a note about that | 11:25 |
| markus_z | sfinucan: OK, I'm going to throw my 2 cents at the ML post | 11:25 |
| lyarwood_ | mdbooth: yeah sorry I mean it's just used by the drivers to detach not cinder to terminate the connection | 11:26 |
| *** shaohe_feng has quit IRC | 11:26 | |
| lyarwood_ | mdbooth: so in the case where we don't call for a detach we just need it to check if there's stashed connector | 11:27 |

| mdbooth | lyarwood_: It's a good idea, as long as we don't fail if we can't | 11:34 |

| *** shaohe_feng has joined #openstack-nova | 11:37 | |
| mdbooth | We don't do that right now, and it's an optimisation I think | 11:37 |
| kashyap | sdague: There we go - https://review.openstack.org/319209 | 11:38 |
| mdbooth | I would assume that this would almost always fail, either because the source compute isn't there, or because it has been down and come back up again, clearing out volumes in the process | 11:38 |
| sdague | gibi: seems fine to me, getting dansmith to check it out would be good | 11:38 |
| mdbooth | However, it would be a good addition anyway, I think | 11:38 |
| mdbooth | Perhaps a separate patch? | 11:38 |
| gibi | sdague: thanks | 11:38 |
| lyarwood_ | mdbooth: well local rebuilds would be fine, it's just remote rebuilds with the src host down that could fail. | 11:39 |
| lyarwood_ | mdbooth: happy to follow up with another patch with that in | 11:39 |
| gibi | dansmith: Could you check https://review.openstack.org/#/c/286675/ (versioned notificaton spec) please? It seems there is an agreement on the direction but we need your opinion. | 11:39 |
| mdbooth | Right, but that's the only case where would would even try this, right? | 11:39 |
| mdbooth | Not saying it's bad, just that it's probably not worth complicating this patch with it | 11:40 |
| lyarwood_ | mdbooth: ah right I see what you're saying, so we would only try the rpcapi call *if* we were remote | 11:40 |
| mdbooth | Yes | 11:40 |
| lyarwood_ | mdbooth: I was just going to replace the _detach_volume call with the rpcapi call | 11:40 |
| mdbooth | Was that not what you were thinking? | 11:40 |
| lyarwood_ | mdbooth: so we always callback to the source host | 11:41 |
| lyarwood_ | mdbooth: even if it's local | 11:41 |

| johnthetubaguy | lyarwood_: so I am curious why we need that check | 12:49 |
| johnthetubaguy | lyarwood_: oh... rebuild... | 12:50 |
| lyarwood_ | johnthetubaguy: it's really to avoid the disconnect_volume call on a host that has never connected to the volume in the past. | 12:50 |
| lyarwood_ | johnthetubaguy: yeah during a remote rebuild | 12:50 |
| johnthetubaguy | lyarwood_: so rebuild is called in two cases, evacuate and rebuild, I guess this is for the evacuate path? | 12:50 |
| lyarwood_ | johnthetubaguy: correct yes, I thought you could also ask for a remote rebuild outside of an evacuation | 12:51 |

| *** salv-orlando has joined #openstack-nova | 12:58 | |
| johnthetubaguy | sdague: so I like it, but I don't like how we call shared storage local... maybe no_root_disk:True, but that makes boot from volume odd... | 12:58 |
| sdague | johnthetubaguy: it's more than just root disk | 12:58 |
| sdague | there are 3 disk values (ignoring config drive) | 12:59 |

| lyarwood_ | lpetrut / claudiub ; Hey, do you have any plans to also introduce stable rescues to hyperv in Newton? https://github.com/openstack/nova-specs/blob/master/specs/newton/approved/virt-rescue-stable-disk-devices.rst | 13:00 |
| sdague | johnthetubaguy: but, the point is, the high level intend is "I don't want local disks at all" | 13:01 |
| lyarwood_ | lpetrut / claudiub ; iirc you needed https://review.openstack.org/#/c/248029 before you could look at this for hyperv. | 13:01 |
| johnthetubaguy | sdague: root_disk_must_be_volume:True? although I would like a better name | 13:01 |
| sdague | which means we shouldn't even report them | 13:01 |
| sdague | like we wouldn't return, disk, swap, ephemeral | 13:01 |
| sdague | in flavor | 13:01 |
| *** sacharya has quit IRC | 13:02 | |
| johnthetubaguy | sdague: ah... yeah, that is much neater | 13:02 |
| sdague | the API should be about intent, not about details | 13:02 |
| tpatzig | sdague: i thought we will not create an additional API field local_disks? local_disks should only be as column in the db? | 13:02 |
| johnthetubaguy | I was thinking about the use case of boot from volume with local ephemeral disks, but its a slightly odd use case | 13:03 |
| sdague | johnthetubaguy: that's such an edge case we should wait for someone to come forward with it | 13:03 |
| sdague | tpatzig: that's the current spec, but I think it's actually making the representation to the user way too confusing | 13:03 |
| tpatzig | ok. i just followed the concerns of lascii | 13:04 |
| sdague | let me go read his bit | 13:04 |
| *** edleafe is now known as figleaf | 13:05 | |
| sdague | tpatzig: right, so your original spec had "volume": 10 | 13:05 |
| sdague | I wouldn't want to do that | 13:06 |
| tpatzig | ok | 13:06 |
| sdague | maybe once lascii gets around | 13:06 |
| sdague | we can do a quick real time discussion | 13:06 |
| tpatzig | https://review.openstack.org/#/c/267673/8/specs/newton/approved/flavor-root-disk-none.rst@128 | 13:06 |
| tpatzig | that was his comment regarding a new column | 13:07 |
| *** kfarr has quit IRC | 13:07 | |
| lpetrut | lyawrwood_: setting the boot order will work in this case only for generation 2 vms, so for generation 1 VMs we'd still have to stick with the 'old' behavior. | 13:07 |
| lpetrut | lywrwood_ we were considering having two different workflows based on the VM generation but that seemed like an overkill | 13:08 |
| sdague | right, so I think that lascii was concerned we'd still display and accept these fields in the API | 13:08 |
| sdague | and what I'm saying, is we would not | 13:08 |
| tpatzig | i'm also more in favor of having local_disks column in the db and a new field local_disks in the api. to have that mapping clear | 13:08 |
| sdague | "local_disk": False means there would be no reporting of swap, root, ephemeral at all | 13:09 |
| *** shaohe_feng has quit IRC | 13:09 | |
| tpatzig | exactly | 13:09 |
| *** daemontool_ has quit IRC | 13:09 | |
| tpatzig | only block_device mapping | 13:09 |
| *** shaohe_feng has joined #openstack-nova | 13:09 | |
| tpatzig | with dest_type volume are then allowed | 13:09 |
| *** ctrath has joined #openstack-nova | 13:09 | |
| johnthetubaguy | so one idea, is do we actually want the flavor to include the "default BDM", rather than what we have today | 13:10 |
| *** xyang1 has joined #openstack-nova | 13:10 | |
| johnthetubaguy | so in this case, the default BDM would be {} | 13:10 |
| johnthetubaguy | actually thats dumb, because we only really want a subset of the BDM | 13:11 |
| sdague | johnthetubaguy: yeh, I was going to say, that's leaking out a lot of stuff | 13:11 |
| sdague | that makes transitions in the future harder | 13:11 |
| johnthetubaguy | I am thinking about how we have to give people three ephemeral disks by default, for our larger flavors | 13:12 |
| johnthetubaguy | hence the overthinking it | 13:12 |
| tpatzig | with local_disks=False can't we just report None for root, ephemeral and swap? | 13:13 |
| sdague | tpatzig: I don't want to report anything for those keys | 13:13 |
| sdague | the keys now become optional | 13:13 |
| tpatzig | ok.fine | 13:13 |
| sdague | because None is a type change anyway, so everyone's code would break on it | 13:14 |
| sdague | if people are going to have to update code, might as well just be a lot more explicit about it | 13:14 |
| lascii | sdague: tpatzig I'm back | 13:14 |
| johnthetubaguy | sdague: I am trying to remember when we hit issues with optional keys in the past, was that in the response? | 13:14 |
| tpatzig | but the default (local_disks=True) is still to have these keys mandatory | 13:14 |
| sdague | tpatzig: yes, if local_disks: True, then those keys exist | 13:15 |
| lascii | sdague: I think you and I are on the same page here. I want flavors to make sense, and the size values get weird when volume are involved | 13:15 |
| *** rlrossit has joined #openstack-nova | 13:15 | |
| lascii | not displaying them with no local disk would be grand | 13:15 |
| sdague | lascii: right, I agree | 13:15 |
| johnthetubaguy | I am not sure about the "local" bit, but I agree with the intent, and general direction | 13:16 |
| sdague | lascii: ok, so to do that in a programatic way, I think we need a new key in the flavor API which is the local_disks boolean | 13:16 |
| sdague | so that people don't have to do key checks, they can know that key is always there, and if it's True another set of keys will be as well | 13:16 |
| *** READ10 has joined #openstack-nova | 13:16 | |
| sdague | plus it makes the flavor create side easier to validate | 13:16 |
| lascii | that works for me, but there's still an unadressed bit which is unrelated to this spec | 13:17 |
| sdague | lascii: ok, which part is that? | 13:17 |
| sdague | johnthetubaguy: why is "local" an issue for you? ceph? | 13:17 |
| lascii | booting from a volume with a flavor which allows local disks is still off | 13:17 |
| johnthetubaguy | sdague: yeah, our "shared" local disk stuff | 13:18 |
| sdague | johnthetubaguy: having a cluster filesystem is still "local" in some sense | 13:18 |
| sdague | you've just managed the storage at a different layer | 13:18 |
| lascii | sdague: I think if we carry data from a volume into instance.flavor rather than the flavor itself it starts to make more sense | 13:18 |
| johnthetubaguy | sdague: yeah, true, I think its a hangover from the XenServer API thats stuck in my head, it calls those remote, I think | 13:19 |

| sdague | lascii: yeh, I've not quite parsed that? maybe I need more words around it. | 13:20 |
| lascii | johnthetubaguy: I mean make it so that when flavor foo has root_gb 50 and you boot from a volume of size 100 that instance.flavor doesn't say 50 | 13:20 |

| lascii | tpatzig: it's not | 13:21 |
| lascii | this is an existing issue | 13:21 |
| lascii | but if we're updating flavors I'd like to consider this as well | 13:21 |
| lascii | though maybe we punt for now | 13:21 |
| tpatzig | ahh you mean beacuse if you boot from volume the root_gb value is meaningless | 13:22 |
| lascii | yes, exactly | 13:22 |
| *** salv-orlando has quit IRC | 13:22 | |
| johnthetubaguy | lascii: so longer term, there is some kind of "active instance config" that combines the image metadata, image metadata overides, BDM, PCI devices attached and flavor, I guess | 13:22 |
| sdague | right, at which point we're actually generating that view out of the instance data right | 13:22 |
| lascii | sdague: I was just thinking that when booting from a volume root_gb loses all meaning, so we're addressing not displaying it if the flavor only works with volumes but we haven't addressed the accuracy of it when the flavor does work with local disk | 13:23 |
| sdague | what happens if you trigger a rebuild on that instance? | 13:23 |
| lascii | I think it just reattaches the volume | 13:23 |
| sdague | because root_gb 50 means we're getting a 50 gb disk locally even though we have a 100 gb volume, right? | 13:23 |
| sdague | I thought that was the problem | 13:24 |
| lascii | it doesn't | 13:24 |
| johnthetubaguy | so you don't get that 50 | 13:24 |
| lascii | root_gb is basically meaningless in that case | 13:24 |
| tpatzig | you only get the 100G volume | 13:24 |
| sdague | ok | 13:24 |
| sdague | but, this is really actually related to https://review.openstack.org/#/c/265282/ | 13:25 |
| sdague | right? | 13:25 |
| sdague | because we don't report flavor based on instance details yet | 13:25 |
| lascii | yes | 13:25 |
| johnthetubaguy | do we want to call it local_root_gb? | 13:25 |
| sdague | which, as long as we don't return flavor_id / flavor_name, I'd be fine morphing the returns | 13:26 |
| *** jwcroppe has quit IRC | 13:26 | |
| lascii | johnthetubaguy: maybe. that's most of my concern, just that it's not clear that root_gb loses all meaning when booting from a volume | 13:26 |
| sdague | but we have to be careful returning flavor info that has an id/name and changing the values of disk sizes | 13:26 |
| sdague | lascii: I think we can fix that concern in docs | 13:26 |
| lascii | sdague: right, and I thought your spec didn't return those | 13:26 |
| *** mjura has quit IRC | 13:27 | |
| lascii | sdague: that's fair too | 13:27 |
| sdague | lascii: it doesn't in the current format, but mriedem wanted it to be the full flavor view | 13:27 |
| tpatzig | local_root_gb…but it does not only affect the root disk. it will affect all local disks | 13:27 |
| lascii | tpatzig: sorry, I don't want to hold you up on this. I just wanted to mention it while we're discussing mucking with flavor representations | 13:27 |
| lascii | sdague: okay. this may be a reason not to do that | 13:28 |
| sdague | johnthetubaguy: are you suggest we change out all the flavor keys inthis one go? | 13:28 |
| *** EinstCrazy has quit IRC | 13:28 | |
| sdague | disk => local_root_gb, swap => local_swap_gb, ....:ephemeral => local_ephemeral_gb ? | 13:28 |
| tpatzig | lascii: np. i'm also a friend of doing it right, than doing it quick | 13:29 |
| johnthetubaguy | I wasn't, but that is more consistent | 13:29 |
| *** EinstCrazy has joined #openstack-nova | 13:29 | |
| dansmith | gibi: okay, I have it open but I have an early meeting I have to do first | 13:29 |
| sdague | so, the consistency would be nice... that being said, we actually have docs now | 13:29 |
| sdague | so, zomg, someone not reading the code might understand thos | 13:29 |
| *** shaohe_feng has quit IRC | 13:29 | |
| lascii | that's crazy talk | 13:30 |
| *** shaohe_feng has joined #openstack-nova | 13:30 | |
| sdague | parameters aren't ever really self explanatory, being nicer is fine, but I don't know if that's worth the hit | 13:30 |
| *** akshai has joined #openstack-nova | 13:31 | |
| lascii | yeah. I'm one the side of wanting this addressed, but wanting something better than a parameter rename. | 13:31 |
| *** dansmith is now known as superdan | 13:31 | |
| lascii | like full flavor decomposition or something else radical | 13:31 |
| lascii | so I think it's best not to tie it into what tpatzig is doing | 13:31 |
| sdague | oh, we don't quite have docs - https://review.openstack.org/#/c/314133/ | 13:32 |
| *** smatzek has quit IRC | 13:32 | |
| sdague | lascii: right, so we could move forward with 1 new key, local_disks, which is a boolean | 13:32 |
| sdague | drop the non relevant keys when it's False | 13:32 |
| sdague | and deal with all the rest of the flavor things separately | 13:32 |
| openstackgerrit | Anusha Unnam proposed openstack/nova: Improve the help text for compute timeout_opts https://review.openstack.org/317693 | 13:32 |
| lascii | yeah, that's fine with me | 13:33 |
| *** vladikr has joined #openstack-nova | 13:33 | |
| lascii | that does leave open what to do with older microversions | 13:33 |
| sdague | because, it will change again once the placement API is fully formed and we're using it I think | 13:33 |
| *** chuck__ is now known as zul | 13:33 | |
| johnthetubaguy | yeah, +1 | 13:33 |
| *** ayoung has joined #openstack-nova | 13:33 | |
| sdague | lascii: as in what to display? | 13:33 |
| johnthetubaguy | I wonder about not doing the drop of the non-relevant keys, for the same argument | 13:33 |
| lascii | sdague: yes | 13:33 |
| johnthetubaguy | just 0 right? | 13:34 |
| *** thorst has quit IRC | 13:34 | |
| johnthetubaguy | for older ones | 13:34 |
| lascii | 0 already has a meaning | 13:34 |
| sdague | so if local_disks=False in the db, I would return 0s across the board | 13:34 |
| tpatzig | ok. sounds good for me. one new api key and a new column 'local_disks' | 13:34 |
| *** rodrigods has quit IRC | 13:34 | |
| *** rodrigods has joined #openstack-nova | 13:34 | |
| sdague | yes it has meaning, but it's meaning was weird and confusing | 13:34 |
| *** laszloh has quit IRC | 13:34 | |
| johnthetubaguy | so I see this a bit like discoverable policy... | 13:35 |
| tpatzig | 0 for root_gb already means, take the size of the glance image | 13:35 |
| johnthetubaguy | if you use the old microversion you can't tell the flavor requires you to use a volume | 13:35 |
| sdague | johnthetubaguy: right, exactly | 13:35 |
| johnthetubaguy | you get a nice 400 error if you do though | 13:35 |
| sdague | yeh, I think that's fine | 13:35 |
| johnthetubaguy | the alternatives seem to break the existing API semantics | 13:35 |
| sdague | yep | 13:36 |
| lascii | so it's basically just display it as is and error based on something the user can't see | 13:36 |
| johnthetubaguy | I suppose there is a choice there, old microversions could have something error with a 400 error in a new place | 13:36 |
| *** rk4n has quit IRC | 13:36 | |
| johnthetubaguy | lascii: it sounds terrible when you phrase it like that, but yes | 13:36 |
| lascii | it's not great. but it may be what we need to do | 13:37 |
| sdague | lascii: the 400 error can return a message about what is going on | 13:37 |
| *** sridharg has quit IRC | 13:37 | |
| lascii | yep | 13:37 |
| sdague | "This flavor has local_disks=True, use microversion > 2.29 to see more details" | 13:38 |
| *** rk4n has joined #openstack-nova | 13:38 | |
| lascii | okay. I'm on board. Maybe someone else will comment on the spec with other ideas | 13:38 |
| *** salv-orl_ has quit IRC | 13:38 | |
| superdan | bauwser: I read something last night that made me think the solution you pushed on top of my set is not right | 13:39 |
| sdague | tpatzig: this all seem good? | 13:39 |
| tpatzig | so we display 0 for all three, when local_disks=False? | 13:39 |
| superdan | bauwser: I had a fix but never pushed.. I'm going to push that now | 13:39 |
| sdague | tpatzig: for older microversions | 13:39 |
| bauwser | superdan: I updated your change | 13:39 |

| bauwser | superdan: why so ? | 13:39 |
| *** rk4n has quit IRC | 13:39 | |
| lascii | tpatzig: so I think how this would actually work is flavor create when given local_disks=False should set the 0s | 13:39 |
| superdan | bauwser: I think you want to use the mysql dialect to get it to apply correctly | 13:40 |
| *** shaohe_feng has quit IRC | 13:40 | |
| lascii | tpatzig: then the api will just display what's there, don't special case it | 13:40 |
| sdague | lascii: ah, good point | 13:40 |
| superdan | bauwser: we do this other places where we have a mysql-specific thing | 13:40 |

| *** shaohe_feng has joined #openstack-nova | 13:40 | |

| danpb | yeah, agreed - i think the discussion around fpga has gone way off into weeds about trying to solve the problem in a totally optimal way for everyone | 14:49 |
| danpb | where as we should really just start totally simple with minimal work done by nova | 14:49 |
| sdague | danpb: agreed | 14:49 |
| _gryf | sdague, lascii - ok, nova should not program the fpga | 14:49 |
| danpb | so just make a bunch of assumptions about how the fpga and programmed / split up / etc | 14:49 |
| _gryf | but maybe it may notify somehow other service to do this before vm will land? | 14:50 |
| danpb | the same way nova doesn't try to get the absolute most theoretically perfect NUMA fit for everything | 14:50 |
| danpb | it just applies a simplified model that works well enough most of the time | 14:50 |
| sdague | _gryf: maybe in the future, at this point we're going to assume you mange the fpga fleet completely independently | 14:50 |
| johnthetubaguy | it feels more like how cinder gets the image into a volume | 14:50 |
| *** ljxiash has joined #openstack-nova | 14:51 | |
| lascii | _gryf: you and jaypipes were going to chat about this right? It was going to start mostly about how to expose fpga resources the the scheduler, assuming they're already programmed | 14:51 |
| _gryf | lascii, that's right | 14:51 |
| *** shaohe_feng has quit IRC | 14:51 | |
| _gryf | lascii, ok, I get the point, and totally agree | 14:52 |
| _gryf | lascii, one step at a time | 14:52 |

| lascii | yeah | 14:52 |
| *** sudipto has joined #openstack-nova | 14:52 | |
| lascii | it's similar to the ironic-composer in a way, which we don't have integrated into Nova yet either | 14:52 |

| *** shaohe_feng has joined #openstack-nova | 14:52 | |

| sdague | it's a backlog spec | 14:53 |
| _gryf | sdague, yes | 14:53 |
| _gryf | that's right | 14:53 |
| _gryf | it is not ment to land on newton | 14:53 |
| _gryf | it was rather a place to start discussion about the use cases fpga can be used for | 14:53 |
| sdague | _gryf: ok, well it is still important to update it to be clear no one on the nova team agrees to nova owning the fpga programming | 14:54 |

| _gryf | sdague, separate service which would take care about it is aceptable though, isn't it? | 14:55 |

| macsz | markus_z: question about config options - i noticed that there are to approaches on where asterisk is used | 14:55 |
| macsz | markus_z: first is to use it to enumerate headline ("Services which consume this" / "Related options" etc (conf/cert.py) | 14:55 |
| macsz | markus_z: second is to use it to enumerate items under a headline (conf/cells.py) | 14:55 |
| macsz | markus_z: which approach is advised? are both of them correct? isn't it against consistency? | 14:55 |
| thorst | danpb: mmandel from my team was wanting to help out with this. Do you think a tempest test would be the best place to start helping? | 14:55 |
| _gryf | there still should be a way to wait for programming process finished before the vm can use such resource | 14:55 |
| sdague | _gryf: yeh, it seems like you really want an fpga fleet manager that puts a programmer out on nodes that can be reprogrammed, and you work out making the right number available and exposed back to the placement engine | 14:56 |
| _gryf | sdague, yes, something like thos | 14:56 |

| jroll | lascii: ironic-composer? | 14:57 |
| lascii | jroll: is that not a thing? now I need to find what I was thinking of | 14:58 |

| jroll | lascii: not by that name, afaik :) | 14:58 |
| *** rk4n has quit IRC | 14:58 | |
| markus_z | macsz: using it for enumerating headlines shouldn't be the case | 14:58 |
| markus_z | macsz: But I don't see it *this* strict | 14:59 |
| markus_z | macsz: As long as the ops get the idea of the option, I'm fine with it | 14:59 |
| markus_z | macsz: My long term goal was that this is valid rst format to be reused in the configuration reference manual. | 15:00 |
| macsz | markus_z: so maybe, just for the sake for consistency, we should remove asterisks in headlines? | 15:01 |
| markus_z | macsz: Would be good, but I won't -1 for that | 15:01 |
| macsz | markus_z: its ultra nit, but still - i am a fan of consistency ;) | 15:01 |

| _gryf | sdague, it smells like that new project called Nomad. It is not started yet, they have the idea on the wiki pages, but no code whatsoever.

| annegentle | hi sneti all the API related bugs were sent to nova. That looks like one that originally came over from DocImpact, so it probably went from openstack-manuals to openstack-api-site to nova. If you sense that quotas for server groups are already documented in http://developer.openstack.org/api-ref/compute/#server-groups-os-server-groups then you can likely close the bug. | 15:33 |

| sneti | annegentle, thank you!! | 16:07 |
| mdbooth | superdan: Why would it change? | 16:07 |
| *** daemontool has joined #openstack-nova | 16:07 | |
| danpb | you can replace image content in glance at any time can't you | 16:07 |
| superdan | mdbooth: you can update the image, right? | 16:08 |
| mdbooth | danpb: iiuc (not a certainty, hence I'm asking) they're immutable | 16:08 |
| danpb | so you may have cached image id 7 locally, but its could have changed in glance since | 16:08 |
| superdan | glance image-update | 16:08 |
| mdbooth | orly | 16:08 |
| * mdbooth tries to think how many things that breaks | 16:08 | |
| superdan | mdbooth: infinity things I'm sure | 16:08 |
| danpb | or the more obvious case that disk bit errors are entirely likely these days with huge storage sizes | 16:09 |
| mdbooth | I'm pretty sure it breaks migration with qcow2 disks | 16:09 |
| *** daemontool_ has quit IRC | 16:09 | |
| danpb | so having a checksum is not entirely wateful | 16:09 |
| superdan | and you can image-upload with a given id, so I'm sure you can do it | 16:09 |
| mdbooth | We just download the backing image from glance. There's no versioning involved. | 16:09 |
| *** Sukhdev has quit IRC | 16:09 | |
| *** sfinucan has quit IRC | 16:10 | |
| mdbooth | So if you update the glance image that an instance is based on, then move it, it's badly borked. | 16:10 |
| danpb | mdbooth: yep, it's entirely possible migration is fubar in that way | 16:10 |
| mdbooth | Surely that can't be right. | 16:10 |
| *** edand_ has joined #openstack-nova | 16:10 | |
| danpb | migration [n]: a feature that break assumptions made everywhere else in the code base | 16:10 |
| superdan | danpb: heh | 16:11 |
| mdbooth | Well it can break single-host too, right? | 16:11 |
| superdan | mdbooth: yes | 16:11 |
| *** Sukhdev has joined #openstack-nova | 16:11 | |
| mdbooth | So you've got 2 instances, 1 created before the change, 1 after | 16:11 |
| superdan | also entirely possible that they were not mutable until glance was split out | 16:11 |
| mdbooth | Presumably we had to overwrite something in the image cache | 16:11 |
| mdbooth | Now we reboot instance 1 and it's borked | 16:11 |
| superdan | yep | 16:12 |
| *** zz_dimtruck is now known as dimtruck | 16:12 | |
| mdbooth | I don't even think writing to the image cache considers this | 16:12 |
| *** Sukhdev_ has joined #openstack-nova | 16:12 | |
| mdbooth | So in fact, I'm pretty sure that if you change it, then boot instance 2 on a host | 16:12 |
| superdan | mdbooth: I like how you keep acting surprised ;) | 16:12 |
| danpb | mdbooth: arguably the image cache should be storing images based on their stringified checksum | 16:12 |
| mdbooth | It will continue to use the old one | 16:12 |
| *** sdake has quit IRC | 16:12 | |
| danpb | rather than based on name or image-id or whatever | 16:12 |
| superdan | danpb: problem is that's super expensive to calculate on a 120G image | 16:13 |
| superdan | on each download.. | 16:13 |
| superdan | although glance does store a checksum, IIRC | 16:13 |
| * mdbooth just thought glance images were immutable | 16:13 | |

| *** shaohe_feng has joined #openstack-nova | 17:38 | |
| lascii | adelia: as far as I know you just have to check the code | 17:39 |
| lascii | like http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/api.py#n173 | 17:39 |
| lascii | for compute | 17:39 |
| *** daemontool_ has quit IRC | 17:39 | |
| lascii | os_compute_api is used in the api/openstack/compute tree I believe | 17:40 |
| adelia | awesome, thank you | 17:40 |
| adelia | yeah, I haven't compared them exhaustively, but so far it looks like the os_compute_api: rules are the only ones that can be directly applied to the API reference | 17:40 |
| openstackgerrit | Maciej Szankin proposed openstack/nova: config options: improve help netconf https://review.openstack.org/319384 | 17:41 |
| lascii | yeah. there used to be the compute rules and with the introduction of the v2.1 API it was decided to move them up into the API code and thus os_compute_api came into being | 17:41 |
| lascii | and with the removal of v2 code the compute rules will go away | 17:42 |
| lascii | so which ones are used actually depends on which API version is being used | 17:42 |
| adelia | ahh I see. that clears a lot up | 17:42 |

| *** dmk0202 has joined #openstack-nova | 18:50 | |
| lascii | auggy: definitely. there are still some nova-manage patches that need to merge, but the general idea is to get grenade using them to do a non-cells->cellvs2 migration | 18:50 |
| auggy | and by non-cells->cells2 migration, you mean take a non cells openstack and make it use cells v2 | 18:51 |
| lascii | exactly | 18:51 |
| lascii | like having it run https://review.openstack.org/#/c/301273/ | 18:51 |
| auggy | right | 18:52 |
| auggy | lascii: ok cool, is there anything i can read up on on patching devstack or setting up grenade things? or would i be updating an existing job? | 18:52 |
| auggy | sorry if i'm asking clueless questions ;) this is part of why i thought this might be a good thing for me ;) | 18:53 |
| lascii | I've never touched grenade. sdague or superdan might be able to point you in a direction | 18:53 |
| lascii | and the plan is to update the current grenade job | 18:53 |
| auggy | lascii: alright, cool, where does that job currently live in repo? | 18:54 |
| *** tonytan_brb has joined #openstack-nova | 18:56 | |

| *** ijw has joined #openstack-nova | 18:57 | |
| *** shaohe_feng has quit IRC | 18:57 | |
| lascii | so grenade seems to be at http://git.openstack.org/cgit/openstack-dev/grenade/tree/ and some of the config at http://git.openstack.org/cgit/openstack-infra/project-config/tree/jenkins/jobs/devstack-gate.yaml?id=31ca25915c8621cfdf11bdb8758ce9b8b6af2c05 | 18:58 |
| *** shaohe_feng has joined #openstack-nova | 18:58 | |
| lascii | auggy: yeah, we would like multinode | 18:59 |
| clarkb | oh hey I know things about this maybe | 18:59 |
| auggy | hey clarkb ! | 18:59 |
| lascii | there are some thoughts at the bottom of https://etherpad.openstack.org/p/nova-cells-testing which may not be entirely clear | 18:59 |
| auggy | clarkb: i'm volunteering to add a non-cells->cellsv2 migration job to grenade and just figuring out how to do that :) | 18:59 |
| auggy | s/job/test/ you know what i mean ;) | 18:59 |
| lascii | to start it would be good to have one node running the api side and cell0, then another node running a separate cell | 19:00 |
| auggy | lascii: yeah i was looking at that testing stuff to get an idea | 19:00 |
| clarkb | auggy: are are two main ways we can or have triggered grenade in the past. The first is doing a previous branch to current branch type upgrade of all existing service. The second is nova-net to neutron or novas baremetal things to ironic where you replace services | 19:00 |
| clarkb | auggy: for the replace services case we have done the upgrade within a branch release so mitaka to mitaka version of the different components | 19:00 |
| *** tonytan4ever has quit IRC | 19:00 | |
| auggy | lascii: ok, do you want api and cell0 as seperate cells or do you want them both in the same cell? | 19:01 |
| clarkb | auggy: I think this comes down to what you expect the transition to be like for cells, is it eg a switch that will happen between branches for everyone are are they more like separate components that you are swapping out | 19:01 |
| lascii | auggy: they can share a db and message queue, so they'll be separate cells but share some components | 19:01 |
| *** ijw_ has joined #openstack-nova | 19:01 | |
| auggy | lascii: ok | 19:01 |
| auggy | clarkb: lascii please correct me if i'm wrong, but i believe we have a migration function in the same branch | 19:02 |
| lascii | yes | 19:02 |
| auggy | and we want to check that that migration works properly | 19:02 |
| lascii | it's not swapping components | 19:02 |
| clarkb | ok so this may be a third new and exciting type of grenade test | 19:02 |
| *** ijw has quit IRC | 19:02 | |
| auggy | hehe | 19:02 |
| lascii | you could do it as part of M->N migration, or N->N | 19:02 |
| clarkb | lascii: which of those two do you expect to prescribe? | 19:03 |
| auggy | seems to me like N->N would be a good starting point | 19:03 |
| lascii | yeah. I'm thinking that people would like to upgrade first, then migrate | 19:04 |
| auggy | yeah i had the same thought but i figure you all know better than me | 19:04 |
| clarkb | for M -> N I think you can use all of the existing devstack-gate machinery and copy pasta from the existin jenkins jobs. What you will end up changing is likely a config in grenade itself that triggers the migration between the two | 19:04 |
| *** lpetrut has joined #openstack-nova | 19:04 | |
| auggy | also N->N for a first test setup means less variables to go wrong that have nothing to do with doing the actual migration | 19:05 |
| auggy | so we can make sure our test actually works | 19:05 |
| auggy | clarkb: ok cool | 19:05 |
| clarkb | auggy: lascii: probably a good place to start would be to create an experimental job that runs against nova and grenade that has some config set, then start pushing patches to grenade to have it run | 19:05 |
| clarkb | that will allo wyou to iterate and see the results as you go | 19:05 |
| *** gzhai2 has joined #openstack-nova | 19:05 | |

| superdan | sdague: yeah the 8GB config drive thing came up at summit | 19:35 |
| superdan | they seemed fine with it :D | 19:35 |
| sdague | superdan: well, in the current spec there is actually this more complicated slice thing | 19:36 |
| superdan | oh, okay I haven't read that | 19:36 |
| superdan | I'm -1 on that anyway until storage pools gets done | 19:36 |
| sdague | which, I kind of would like to avoid just because complexity | 19:36 |
| superdan | as this is just adding more crufty code | 19:36 |
| superdan | yeah | 19:36 |
| sdague | hence the trying to think about any other way to do things | 19:36 |
| sdague | and a tmpfs for config drives doesn't seem like the worst idea | 19:37 |
| sdague | you sacrifice a little ram, but then don't need disk | 19:37 |
| superdan | well, libvirt doesn't recreate them on boot, | 19:37 |
| superdan | so after you restart the compute node nothing would boot | 19:37 |
| superdan | we'd need to change the drivers to make them recreate if missing all the time | 19:37 |
| sdague | ah... I was wondering that | 19:37 |

| superdan | leakypipes: you're talking about the case where we have some instances accounted for in the old way of "free_gb" and some accounted for with allocations, potentially with some overlap at some point? | 21:12 |
| superdan | I guess my point is, I think this ends up being a thing that people will cut over to after everything is happy | 21:12 |
| superdan | i.e. we continue scheduling with the old filters until everything has migrated to allocations, | 21:13 |
| superdan | then they change scheduler config and restart the scheduler | 21:13 |
| superdan | which would mean we don't need to try to subtract the allocations from the free_* attributes | 21:14 |
| superdan | we just continue reporting free_gb like we did before, and either use total_gb-free_gb, or inventory-allocation | 21:14 |
| superdan | but not a mix of both, | 21:14 |
| superdan | especally since we're now not zeroing the compute node fields anymore given that we moved inventory to the api db | 21:15 |
| superdan | or will move | 21:15 |

| lascii | if we're just going to remove these I guess I don't really care, just wanted it to be consistent | 21:23 |
| lascii | it can just be added to sdagues patch | 21:23 |

| lascii | well if you'd throw up a softball patch for friday afternoon reviews we could all be relaxed going into the weekend | 21:29 |
| leakypipes | superdan: what I'm saying is that unless we do the migration of allocation information atomically (for the compute node), there will be no way for the scheduler to determine, as you say "until everything is migrated to allocations". Because *some* instances on the compute host will have their allocations records written and others will not (and will be updating the total_gb/free_gb fields on | 21:29 |
| leakypipes | the compute node). | 21:29 |
| superdan | lascii: I have one actually :) | 21:29 |

| *** markvoelker has quit IRC | 21:30 | |
| lascii | excellent | 21:30 |
| superdan | leakypipes: right but I don't understand why that matters | 21:30 |
| superdan | leakypipes: inventories but no allocations means the compute nodes look empty, so your new filter will be largely a no-op right? | 21:31 |
| leakypipes | superdan: which means that the thing in the ComputNode object that you are currently relying on to determine if the inventories/allocations have been migrated (whether the inv_memory_mb_used field is NULL or not) cannot be used to determine if the allocations have been migrated (since you will only know that *some* ofthe instanes for the compute node had been mgrated, not all of them on that | 21:31 |
