| markus_z | kashyap: I excluded it from the mail to avoid a meta-discussion what a "rc-blocker" *really* is... I'm not sure if this was clever or stupid. | 07:30 |
| *** markvoelker has quit IRC | 07:30 | |
| kashyap | No worries, if someone is _really_ interested, they'd go look it up anyway. | 07:31 |
| markus_z | kashyap: I had the hope that the subteam leaders make reasonable decisions here. | 07:31 |
| kashyap | (Also, it's not a meta-discussion, perfectly on-topic.) | 07:31 |
| bauzas | markus_z: kashyap: are you okay to have a google hangout for the bug triage? | 07:32 |
| bauzas | anyone can just go to the hangout if he wants to help us | 07:32 |

| bauzas | markus_z: meh, then let's open an etherpad | 07:34 |
| kashyap | Yep, it's perfectly on-topic. Most times this involves looking up, grepping through code, trying to reproduce bugs, doing stuff in LP, anyway. | 07:35 |
| markus_z | bauzas: The hurdle to step in would be lower too, if we do it here. | 07:35 |
| markus_z | https://etherpad.openstack.org/p/liberty-nova-priorities-tracking This launchpad has already a topic for this. | 07:36 |
| bauzas | to be clear, I'm reviewing all the changes to see if those are good or not | 07:36 |
| bauzas | https://etherpad.openstack.org/p/liberty-rc-bug-triage as an example | 07:36 |
| markus_z | bauzas: The etherpad here has already an entry for that. https://etherpad.openstack.org/p/liberty-nova-priorities-tracking | 07:38 |
| *** tdurakov has joined #openstack-nova | 07:38 | |
| markus_z | I'll read through the high prio LP bugs and double-check if they are maybe in progress despite they are in another status. | 07:39 |
| *** whenry has joined #openstack-nova | 07:39 | |
| bauzas | markus_z: okay, your call | 07:39 |
| bauzas | markus_z: my approach is to see the current changes and see if they are Closes-Bug | 07:40 |
| bauzas | markus_z: if the patch is okay, I'm just considering it as liberty-rc-potential, provided a Jenkins check happened quite recently | 07:40 |
| *** jlanoux has joined #openstack-nova | 07:40 | |
| bauzas | markus_z: if not, I'm rebasing locally the change to see if it merges | 07:41 |
| bauzas | not running the tests tho, I leave that for the gate | 07:41 |
| markus_z | Maybe it makes sense to reply to the ML that the authors/committers of those changes should double-check by themself? | 07:42 |
| bauzas | markus_z: that's up to you | 07:42 |
| bauzas | markus_z: I'm just marking the tag if I feel it's a good candidate for RC, if not I prefer to leave the field blank | 07:43 |
| bauzas | markus_z: but that means I'm still reviewing the change - really reviewing and voting I mean | 07:43 |
| markus_z | bauzas: Yes, sounds reasonable. | 07:44 |
| markus_z | The real blocker items will be targeted with the milestone "liberty-rc1" then. It's just to get a first set of blocker candidates. | 07:45 |
| markus_z | kashyap: If you like, you could have a look at those reviews too? To split things up, I mean. | 07:46 |
| kashyap | markus_z: These, you mean? - https://goo.gl/nMyCzu | 07:47 |
| markus_z | kashyap: Yes, that's the one. | 07:48 |
| kashyap | Okay. I'm already looking through bugs tagged w/ 'potential' for areas where I can meaningfully comment. | 07:48 |
| markus_z | bauzas: kashyap: Great! Thanks for your effort, to both of you! | 07:49 |

| *** moshele has joined #openstack-nova | 09:28 | |
| danpb | markus_z: we don't treat it based on releases | 09:28 |

| alex_xu_ | bauzas: the novaclients didn't now the API which newer than it | 09:46 |
| bauzas | alex_xu_: IIUC, a novaclient supporting 2.21 wouldn't be compatible with an API 2.10 as per https://github.com/openstack/python-novaclient/blob/master/novaclient/api_versions.py#L144 | 09:46 |
| bauzas | (I mean an API expression max_version equals to 2.10) | 09:47 |
| alex_xu_ | bauzas: that means the client didn't support 2.21. | 09:48 |
| bauzas | alex_xu_: what do you mean by "novaclients don't know newer API versions" | 09:48 |
| *** leseb_ has quit IRC | 09:48 | |
| bauzas | alex_xu_: you mean the client doesn't support 2.10 rather | 09:48 |
| alex_xu_ | bauzas: there is variable mark the max version supported by client, it's at novaclient.__init__.py | 09:50 |
| alex_xu_ | bauzas: called https://github.com/openstack/python-novaclient/blob/master/novaclient/api_versions.py#L144 | 09:50 |
| alex_xu_ | bauzas: sorry, called API_MAX_VERSION | 09:50 |
| alex_xu_ | I can't open github... | 09:50 |
| *** Daisy has quit IRC | 09:51 | |
| alex_xu_ | bauzas: if there is new feature in the API, we need add support in the client, and we need bump that variable | 09:51 |
| *** Daisy has joined #openstack-nova | 09:51 | |
| bauzas | alex_xu_: that I know | 09:52 |
| *** Daisy has quit IRC | 09:52 | |
| bauzas | alex_xu_: sec, giving you git.oo links rather | 09:52 |
| *** Daisy has joined #openstack-nova | 09:52 | |
| bauzas | alex_xu_: so the client exposes http://git.openstack.org/cgit/openstack/python-novaclient/tree/novaclient/__init__.py#n23 | 09:53 |
| bauzas | alex_xu_: if API_MAX_VERSION = 2.11 and API_MIN_VERSION = 2.1, that means that a server having a max version to 2.7 would be compatible right? | 09:54 |
| *** leseb_ has joined #openstack-nova | 09:54 | |
| alex_xu_ | bauzas: yea | 09:54 |
| alex_xu_ | bauzas: sorry, looks like I can't open any link....I guess I need reboot the system... | 09:54 |
| bauzas | alex_xu_: okay, so provided I added a new resource like /foo in 2.8 but my server is still 2.7, what happens with the client calling that resource ? | 09:55 |
| markus_z | bauzas: kashyap: I have some meetings in the next hours and will be hard to reach. Thanks again for your effort here! | 09:55 |
| bauzas | alex_xu_: provided we agreed on the fact that the client is compatible | 09:55 |
| alex_xu_ | bauzas: add new resource in server ? | 09:56 |
| bauzas | markus_z: np, I'll continue to look over those changes | 09:56 |
| alex_xu_ | or client? | 09:56 |
| bauzas | alex_xu_: add new resource in client, mapped to a resource in server with version 2.8, but server is still at 2.7 | 09:56 |
| alex_xu_ | bauzas: ok, I see now. The client will negotiate with server, check the server supported max version. | 09:57 |
| alex_xu_ | bauzas: the client(CLI) always find the most recent version between client and server | 09:57 |
| alex_xu_ | in default | 09:57 |
| bauzas | alex_xu_: so it would call the API but it would get a 404 right? | 09:57 |
| bauzas | alex_xu_: because no code would be deployed | 09:58 |
| *** Daisy has quit IRC | 09:58 | |
| alex_xu_ | bauzas: if you specifiy the 2.8 in the client options, then client will tell you, the server didn't support that | 09:58 |

| claudiub | johnthetubaguy: hello. hyper-v ci is happy with this commit: https://review.openstack.org/#/c/214493/ | 10:12 |

| johnthetubaguy | claudiub: ah, cool, what was needed to fix the CI, I am curious? | 10:13 |
| PaulMurray | ndipanov, I added you to https://review.openstack.org/#/c/223722/ and https://review.openstack.org/#/c/223723/ | 10:14 |
| PaulMurray | ndipanov, these are the patches I mentioned yesterday - sorry took so long | 10:14 |
| PaulMurray | ndipanov, they have to be reworked to make use of bdm as described in the spec | 10:15 |
| claudiub | johnthetubaguy: well, a few bugfixes merged that reduced the amount of random failures on the hyper-v side. there's also been some upgrades / patches / fixes on the hyper-v ci overall. | 10:16 |
| johnthetubaguy | claudiub: cool, do we have the list of important fixes for liberty all tagged with liberty-rc-potential and in the etherpad (of doom)? | 10:17 |
| claudiub | johnthetubaguy: still, I was noticing some instances being stuck in scheduling or building state, but those instances never made it past n-api, for some reason. | 10:17 |

| johnthetubaguy | claudiub: thats curious, do you have logs from that? | 10:18 |
| claudiub | johnthetubaguy: from what I know, we only have a handful of bugfixes overall. this is one of them. i think there are 2-3 patches left, but still waiting for a positive vote from the ci | 10:18 |
| claudiub | johnthetubaguy: i'll have to seach. brb | 10:19 |
| johnthetubaguy | claudiub: cool, when they are all lined up, do ping me, I think I have been through most of those at least once already | 10:19 |

| ndipanov | PaulMurray, ok will take a look! thanks | 10:23 |
| openstackgerrit | Nikola Dipanov proposed openstack/nova: rebuild: RPC sends additional args and claims are done https://review.openstack.org/200485 | 10:23 |

| openstackgerrit | Rui Chen proposed openstack/nova: Execute _init_instance() concurrently https://review.openstack.org/223572 | 10:24 |
| claudiub | johnthetubaguy: also, this is a simple patch, just adding extra logs for live migration and when it fails. We've had some live-migration failures and some extra logging would have been very helpful: https://review.openstack.org/#/c/217822/ | 10:25 |

| openstackgerrit | Jordan Pittier proposed openstack/nova: libvirt:on snapshot delete, use qemu-img to blockRebase if VM is stopped https://review.openstack.org/192736 | 11:05 |
| claudiub | johnthetubaguy: here's an example with many instances being stuck in scheduling state: http://64.119.130.115/220622/5/results.html.gz | 11:06 |
| claudiub | johnthetubaguy: this another run, but with only one instance stuck in scheduling: http://64.119.130.115/214493/12/results.html.gz | 11:06 |
| claudiub | johnthetubaguy: also, since the scheduler doesn't log the instance-id, it's harder to track each instance in the scheduler's logs | 11:07 |
| *** ferest has quit IRC | 11:08 | |
| *** alex_klimov has joined #openstack-nova | 11:08 | |

| johnthetubaguy | claudiub: 2015-09-09 15:42:06.440 DEBUG nova.scheduler.filter_scheduler [req-1dd96b8e-34ed-4cb6-844c-cab45b3f2de8 tempest-ServersTestJSON-1397230889 tempest-ServersTestJSON-1449056735] Selected host: WeighedHost [host: (c2-r1-u17, c2-r1-u17) ram:15774 disk:150528 io_ops:1 instances:1, weight: 0.660617517328] _schedule /opt/stack/nova/nova/scheduler/filter_scheduler.py:167 | 11:12 |
| claudiub | johnthetubaguy: true, but not my favorite tracking method, since you can have multiple requests for the same instance, meaning different request-ids. | 11:12 |
| claudiub | johnthetubaguy: yeah, and afterwards? it just remains in scheduling | 11:12 |
| johnthetubaguy | tdurakov: do ask away, its easier if you send the question, then others can jump in and help you if they know better than me :) | 11:12 |
| *** piyanai has quit IRC | 11:13 | |
| johnthetubaguy | claudiub: you have a single request-id for the create request though | 11:13 |
| claudiub | johnthetubaguy: true | 11:13 |
| *** e0ne has joined #openstack-nova | 11:13 | |
| tdurakov | i'd like to ask you to review my patch, no questions:) | 11:13 |
| tdurakov | there is thread in ml about silent fails during resize | 11:14 |
| tdurakov | we discussed it with alaski, but thread was started to gather more opinions on the problem | 11:15 |
| johnthetubaguy | claudiub: so I have seen this before, we have a bug open for this | 11:16 |
| johnthetubaguy | claudiub: take a look at the end of this nova-compute log: http://64.119.130.115/220622/5/Hyper-V_logs/hv-compute2/nova-compute.log.gz | 11:17 |
| johnthetubaguy | claudiub: nova-compute has totally locked up, somehow | 11:17 |
| johnthetubaguy | claudiub: its a problem I saw with the multi-node job, I think | 11:17 |
| johnthetubaguy | claudiub: i think its when you have a delete instance happing, but you send in a create instance request, or something like that | 11:18 |
| tdurakov | johnthetubaguy, here is the thread: http://lists.openstack.org/pipermail/openstack-dev/2015-August/072224.html | 11:19 |
| johnthetubaguy | tdurakov: yes, I should give that a read | 11:20 |
| johnthetubaguy | tdurakov: its something we have spoken about a lot over the years, and I am really wanting tasks to help fix that, given my conversations with bauzas | 11:20 |
| *** Daisy has joined #openstack-nova | 11:21 | |
| tdurakov | johnthetubaguy, yep task are great | 11:21 |
| *** ociuhandu has joined #openstack-nova | 11:21 | |
| tdurakov | but there should be some verification before task scheduled to run, IMO? | 11:22 |
| johnthetubaguy | tdurakov: part of this is probably a better implementation of --poll in nova-client, using the instance actions would be a good thing | 11:22 |
| johnthetubaguy | tdurakov: some yes, there are always limits | 11:22 |
| johnthetubaguy | earlier errors are easier to deal with | 11:22 |
| tdurakov | johnthetubaguy, there are same checks for live-migration already | 11:22 |
| johnthetubaguy | its a balancing act | 11:22 |
| *** lucasagomes is now known as lucas-hungry | 11:23 | |
| johnthetubaguy | yeah, live-migrate is a disaster zone because of those | 11:23 |
| tdurakov | same pattern i mean | 11:23 |
| johnthetubaguy | yeah, I don't want to see us use any more "call" than we have to from the API, ideally zero | 11:23 |
| *** Guest86825 has quit IRC | 11:23 | |
| claudiub | johnthetubaguy: yeah, i saw that the logs end at 15:42 on node 2 and 15:57 on node 2, but I don't think the services died. I mean, there are still tests passing at 16:25 | 11:24 |
| claudiub | 15:57 on node 1* | 11:24 |
| johnthetubaguy | claudiub: its not dead, its locked up | 11:24 |
| *** beagles__ has joined #openstack-nova | 11:24 | |
| johnthetubaguy | claudiub: seen that a few times, usually turns out to be some deadlock in the way locks are aquired | 11:24 |
| tdurakov | johnthetubaguy, i don't think call are the root cause of l-m problems:) | 11:24 |
| johnthetubaguy | claudiub: given those extra locks just got added, I would look there first | 11:24 |
| tdurakov | and sometimes they are reasonable | 11:25 |
| johnthetubaguy | tdurakov: sure, but we have seen lots of bugs around call's timing out in certain driver implementations and things | 11:25 |
| claudiub | johnthetubaguy: would that even prevent logging? | 11:25 |
| johnthetubaguy | claudiub: it does when the periodic tasks get blocked | 11:25 |
| openstackgerrit | Timofey Durakov proposed openstack/nova: Split instance resize operation into 2 phases https://review.openstack.org/195088 | 11:25 |
| tdurakov | i've updated my patch, that fix this problem with resize. | 11:26 |
| *** bkopilov has quit IRC | 11:26 | |
| johnthetubaguy | tdurakov: so I don't want to merge that until we have liberty released really, thats a very tricky change | 11:27 |
| johnthetubaguy | tdurakov: but we should totally look at those closely once we have mitaka open | 11:27 |
| *** markvoelker has joined #openstack-nova | 11:27 | |
| johnthetubaguy | tdurakov: its a risk of regression issue at this point, and my lack of trust in our testing in that area | 11:27 |
| johnthetubaguy | tdurakov: afraid I have to run to get some lunch, been putting it off a bit, but I am quite hungry now, sorry to run off mid conversation | 11:28 |
| claudiub | johnthetubaguy: you said that we have a bug open for this kind of issue. can you paste the link for it pls? | 11:28 |
| johnthetubaguy | claudiub: been failing to find it, I remember digging into it a bit in the past :S | 11:28 |

| tdurakov | alaski, i heard that you and sbauza are working on long-running task concept for nova. while this is great, such check should not be part of task IMO, so these activities should not intersect, what do you think? | 14:26 |
| bauzas | dansmith: I'd love to write an ice cream manifesto | 14:27 |
| dansmith | +1 | 14:27 |
| *** thangp has joined #openstack-nova | 14:27 | |
| bauzas | tdurakov: well ,Tasks are not only for long-running tasks | 14:28 |
| alaski | tdurakov: I think that an API response should not need to wait for an RPC message to conductor then compute to finish in order to respond | 14:28 |
| *** sayali has quit IRC | 14:28 | |
| bauzas | tdurakov: that's rather better for tracking all the actions related to a specific request | 14:28 |
| alaski | tdurakov: I'm not sure I understand why a task isn't a good fit for this | 14:28 |

| * bauzas could be a very terrible PM | 14:31 | |
| *** artom has joined #openstack-nova | 14:31 | |
| tdurakov | alaski, bauzas, well, I thought that tasks are for smth long-running, so imho there is a place for input verification before task should be scheduled for execution | 14:31 |
| *** openstackgerrit has quit IRC | 14:31 | |
| bauzas | tdurakov: well, tasks are far more than that, it's for having a better way to track where we are | 14:31 |
| *** openstackgerrit has joined #openstack-nova | 14:32 | |
| tdurakov | bauzas, are you planing to have all possible actions with instance as tasks? | 14:32 |
| alaski | tdurakov: as bauzas said they don't need to be long running. I'm very much in support of input verification that can be done upfront, but not if it requires an RPC call to do it | 14:32 |
| bauzas | tdurakov: you should be reading my manifesto | 14:32 |
| tdurakov | bauzas, i've read first version | 14:33 |
| tdurakov | so, are you going to move all actions to task concept? | 14:33 |
| bauzas | which I assume is probably as much exciting as a thristy yak in the winter | 14:33 |
| tdurakov | alaski, what about live-migration? there is already compute level verification with rpc | 14:34 |
| bauzas | tdurakov: live-migration checks done on the conductor are just... heh, terrible IMHO | 14:35 |
| tdurakov | bauzas, no | 14:35 |
| *** nikhil has quit IRC | 14:35 | |
| bauzas | tdurakov: but we mostly miss to track what happens when it goes to the compute | 14:35 |
| tdurakov | i'm about compute level checks | 14:35 |

| tdurakov | smh like that | 14:35 |
| alaski | tdurakov: I think it's a mistake. it was the best option at the time I'm sure, but that doesn't mean we need to copy it | 14:36 |
| bauzas | yeah, you mean touching a file and see we can read it ? :D | 14:36 |
| * bauzas giggles | 14:36 | |
| tdurakov | alaski, how you are going to detect shared storage without such checks?) | 14:36 |
| *** Marga_ has quit IRC | 14:36 | |
| tdurakov | for example | 14:36 |
| bauzas | okay, I think there is a misunderstanding | 14:37 |
| *** Marga_ has joined #openstack-nova | 14:37 | |
| alaski | tdurakov: if the check happens after the API responds it's fine. I don't see why the API response should depend on whether or not there's shared storage | 14:37 |
| *** tongli has quit IRC | 14:37 | |
| *** david-lyle has quit IRC | 14:37 | |
| bauzas | alaski: tdurakov: any change you could give me ? | 14:37 |
| bauzas | because I strongly agree with alaski | 14:37 |
| bauzas | without context | 14:38 |
| bauzas | just because of what he said | 14:38 |
| tdurakov | lol | 14:38 |
| tdurakov | let me figure out | 14:38 |
| tdurakov | tasks are really good idea | 14:38 |
| bauzas | tasks are not unicorns or magical wands that will solve all our problems | 14:39 |
| tdurakov | but tasks is something that you are scheduling, right? | 14:39 |
| *** haomaiwang has joined #openstack-nova | 14:39 | |
| alaski | tdurakov: not necessarily. a reboot could be a task | 14:39 |
| tdurakov | alaski | 14:39 |
| tdurakov | ok, reboot sounds good) | 14:39 |
| tdurakov | for example i've type nova reboot test1 | 14:39 |
| bauzas | technically, moving an host to an aggregate is a task too | 14:40 |
| bauzas | it doesn't change the instances tho | 14:40 |
| tdurakov | what should i see as a response? | 14:40 |
| tdurakov | alaski, ^ | 14:40 |
| *** casusbelli has joined #openstack-nova | 14:40 | |
| tdurakov | accepted? | 14:40 |
| alaski | tdurakov: yes. with a reference to a task url to track | 14:40 |
| *** sayali has joined #openstack-nova | 14:41 | |
| tdurakov | nice) | 14:41 |
| tdurakov | but what if instance dent exist at all? | 14:41 |
| tdurakov | doesn't | 14:41 |
| *** raildo is now known as raildo-afk | 14:41 | |
| bauzas | the API fences that previously | 14:41 |
| *** raildo-afk is now known as raildo | 14:41 | |
| alaski | 404. but that's a check that can be done without waiting on an RPC response | 14:41 |
| *** otter768 has joined #openstack-nova | 14:42 | |
| bauzas | that's already done actually | 14:42 |
| tdurakov | ok, now i see | 14:42 |
| *** diogogmt has joined #openstack-nova | 14:42 | |
| *** jecarey has quit IRC | 14:42 | |
| tdurakov | the main concern is about asking smth from computes, right? | 14:42 |
| alaski | exactly | 14:43 |
| tdurakov | alaski, ok | 14:43 |
| alaski | asking something before the API response can be given | 14:43 |
| tdurakov | buut:-) | 14:43 |
| tdurakov | why we are not afraid to use calls to ask smh from conductor then? | 14:43 |
| bauzas | because that's where the boundary is set | 14:44 |
| tdurakov | lol | 14:44 |
| tdurakov | bauzas, is there reasons to set boundaries there? | 14:45 |
| alaski | I would like to not have calls to conductor either | 14:45 |
| bauzas | alaski: that's actually something synchronous atm | 14:45 |
| tdurakov | alaski, this sounds more reasonable IMO | 14:45 |
| tdurakov | ok, and what about scheduler? | 14:46 |
| alaski | tdurakov: to be clear my only concern here is calls from the nova-api | 14:46 |
| *** otter768 has quit IRC | 14:47 | |
| alaski | which doesn't call to the scheduler afaik | 14:47 |
| tdurakov | if we use tasks, request to scheduler should they be done before task execution? | 14:47 |
| tdurakov | ok | 14:47 |
| tdurakov | alaski, now it seems clearer:) | 14:47 |
| tdurakov | bauzas, alaski thanks:) | 14:48 |
| alaski | tdurakov: awesome | 14:48 |
| alaski | np | 14:48 |
| bauzas | I'm just doublechecking | 14:48 |
| tdurakov | it's a good point to move requests from api to casts:) | 14:48 |
| bauzas | but creating an instance calls the conductor api | 14:49 |
| tdurakov | heh, instance boot, right... | 14:49 |
| bauzas | tdurakov: but the conductor RPC message is a cast, so that's non-blocking | 14:50 |
| alaski | bauzas: the build_instance path is a cast to conductor | 14:50 |

| *** annegentle has quit IRC | 14:54 | |
| flaper87 | sudipto: how familiar are you with nova.image.glance? | 14:54 |
| sudipto | flaper87, if you remember, i had a chat on one of my early mornings - w.r.t to the error code handling you did for the versions dict. | 14:54 |
| flaper87 | sudipto: did you check my previous, lenghty, attempt to refactor this code? | 14:55 |
| flaper87 | sudipto: my memory is terrible and I'd wholeheartedly advice you not to trust it | 14:55 |
| flaper87 | :P | 14:56 |
| sudipto | flaper87, nope, i haven't seen your attempt in the past, but here's the code i had up for review - recently https://review.openstack.org/#/c/222150/ | 14:56 |
| flaper87 | sudipto: but I think I remember, yup | 14:56 |
| flaper87 | :D | 14:56 |
| *** haomaiwang has quit IRC | 14:56 | |

| flaper87 | sudipto: https://review.openstack.org/#/c/144875/ <- this is the last attempt I did. FWIW, despite what the gate says, it worked. The issue with that is that it was a huge refactor and it was quite a risk to just merge it like that | 14:58 |

| flaper87 | sudipto: in the process, I got quite familiar w/ that code and the issues related to it. I wouldn't recommend you to look at the whole patch but rather dedicate time to read this: https://review.openstack.org/#/c/144875/34/nova/image/api.py,cm | 14:59 |
| flaper87 | That's the most important part of that patch | 14:59 |
| * sudipto is reading... | 14:59 | |
| flaper87 | It contains a unified cross-version compatible version of nova.images.api | 14:59 |
| flaper87 | sudipto: I commented everything there and let some sarcasm in for the sake of keeping myself sane in the process | 15:00 |
| flaper87 | :D | 15:00 |

| *** tonytan4ever has joined #openstack-nova | 15:21 | |
| sudipto | flaper87, my idea was to work on small chunks - the direction jaypipes_ had given me was to make sure we use the versions URI - and then slowly start replacing methods that default to 1. | 15:21 |

| *** Marga_ has quit IRC | 15:24 | |
| flaper87 | sudipto: right, you can tell from the patch that splitting this into small chunks can be hard, especially because to use the v2 properly there are some changes that are required in the code that impact other areas in Nova | 15:24 |
| flaper87 | sudipto: we need to work on a spec for Nova to lay down the plan for this work and I'm happy to work with jaypipes on that | 15:24 |
| sudipto | flaper87, ok... | 15:25 |
| flaper87 | There's a draft version that was started in Kilo a second draft in Liberty and I guess we'll come out with a merge between those and the latest findings | 15:25 |
| markus_z | sahid: Would you consider removing your -1 from https://review.openstack.org/#/c/220519 and https://review.openstack.org/#/c/215102 ? | 15:25 |

| openstackgerrit | jichenjc proposed openstack/nova: devref: change error messages no need microversion https://review.openstack.org/218491 | 15:26 |

| *** nkrinner is now known as nkrinner_afk | 15:26 | |
| sudipto | flaper87, sure, in the meantime, i guess the critical bit is the part where nova may need to adapt to some of the changes w.r.t defaulting to v2. I will get a good clue of that from your patch hopefully. | 15:27 |
| sudipto | flaper87, if that's route for now, could you provide your review comments on my patch here: https://review.openstack.org/#/c/222150 | 15:27 |
| flaper87 | sudipto: sure thing, I just starred it | 15:28 |
| sudipto | flaper87, i haven't made any attempt yet to replace anything - just to want to ensure that it's liked first and then proceed on what's needed to make use of it. | 15:28 |

| ndipanov | dansmith, yeah is smth wrong with it? | 16:12 |
| dansmith | nope, was just getting ready to look | 16:13 |
| dansmith | it does change rpc, so we're getting pretty close to having to not do more of that I think, but was going to evaluate at least | 16:13 |

| gsilvis | I have a question about the volume attach/detach API calls. Volume attach returns a JSON object with both "id" and "volumeId" fields. "volumeID" is clearly the ID of the attached volume, and "id" is the id used when deleting the attachment | 17:41 |
| gsilvis | Currently it looks like the values of these two fields is always the same. Is this always true? If so, is there a specific reason for it? | 17:41 |
| mriedem | gsilvis: they are the same value https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/volumes.py#L299 | 17:43 |
| mriedem | gsilvis: i don't know the background, there is probably some reason id or volumeId was added later, and we can't drop one b/c of backwards compatibility | 17:44 |
| *** pixelb has joined #openstack-nova | 17:45 | |
| gsilvis | ah, thanks for the code link | 17:46 |
| *** tdurakov has joined #openstack-nova | 17:47 | |

| mriedem | gsilvis: i would definitely be a backward incompatible change | 17:51 |
| mriedem | *it | 17:51 |
| dansmith | and we'd have to persist the other id so we could honor it | 17:51 |
| mriedem | it would require a microversion, and i'm not sure what the use case is | 17:51 |

| vilobhmm_11 | dansmith : ping | 19:14 |
| dansmith | vilobhmm_11: ack | 19:14 |
| vilobhmm_11 | you remember the other day we talked about client=>sg-api=>sg-driver(db driver)=>object layer => db | 19:15 |
| vilobhmm_11 | in compute node object there are specific calls to service object…which IMHO should also follow similar pattern….https://github.com/openstack/nova/blob/master/nova/objects/compute_node.py#L135 what you think ? | 19:16 |
| vilobhmm_11 | but call going from objects layer to sg layer seems kinda weird so thought will check with you before proceeding ahead | 19:16 |
| vilobhmm_11 | dansmith : ^6 | 19:16 |
| dansmith | vilobhmm_11: yeah, I think that objects calling the sg api is probably wrong | 19:17 |
| vilobhmm_11 | true | 19:17 |
| *** ctrath has quit IRC | 19:17 | |
| vilobhmm_11 | what do you suggest for such cases | 19:17 |
| *** dave-mccowan has joined #openstack-nova | 19:17 | |
| dansmith | vilobhmm_11: at least for the first cut, I think that supports my point that "is this a service" should be a function of the database, regardless of what sg driver we're using, | 19:18 |
| *** pumaranikar has quit IRC | 19:18 | |
| dansmith | and "is this service up" should be a function of the SG api | 19:18 |
| *** tonytan4ever has quit IRC | 19:18 | |
| vilobhmm_11 | but irrespective of that wouldn't https://github.com/openstack/nova/blob/master/nova/objects/compute_node.py#L135 need to make a call to sg layer to get that details ? is that acceptable ? | 19:19 |
| vilobhmm_11 | dansmith : ^^ | 19:19 |
| dansmith | vilobhmm_11: no, because that code doesn't care if the service is up, only that it exists, right? | 19:19 |
| *** sudipto has joined #openstack-nova | 19:21 | |
| vilobhmm_11 | dansmith : agree it checks only if it exist…. but if we could have other objects (like objects.compute_node) making use of objects.service to go through sg layer would be ideal IMHO | 19:23 |
| vilobhmm_11 | before getting service information | 19:23 |
| dansmith | I'm not sure that's the right layer on which to do that | 19:23 |
| *** lpetrut has joined #openstack-nova | 19:23 | |
| dansmith | if it is, then it needs to be a subclass of service that implements a .is_up() method, and we just dump the sg api altogether or something | 19:23 |
| *** ctrath has joined #openstack-nova | 19:24 | |
| melwitt | dansmith: that sounds similar to what I was saying in the spec at the beginning, all service data in db except up/down which goes in sg driver backend | 19:24 |
| dansmith | melwitt: yeah, agree with that.. not sure I agree it should be on the object, but +1 to making SG only responsible for up-ness | 19:24 |
| *** moshele has joined #openstack-nova | 19:24 | |
| *** aix has joined #openstack-nova | 19:25 | |
| *** pumaranikar has joined #openstack-nova | 19:25 | |
| melwitt | dansmith: yeah. I didn't mean it would be on the object. just that sg api abstraction is only for the up/down part | 19:25 |
| *** pumaranikar has quit IRC | 19:26 | |
| dansmith | melwitt: cool, +2 :) | 19:26 |
| dansmith | not really sure why it's called server groups either, since that's overloaded elsewhere | 19:26 |
| *** hemna is now known as hemnafk | 19:26 | |
| vilobhmm_11 | dansmith, melwitt : #1. All service data in respective backend #2. Service data in db but sg api abstraction is only for the up/down part | 19:26 |
| vilobhmm_11 | the spec has been approved with #1 | 19:27 |
| *** alex_klimov has joined #openstack-nova | 19:27 | |
| dansmith | vilobhmm_11: I don't really think it has | 19:27 |
| *** Apoorva has quit IRC | 19:27 | |
| dansmith | vilobhmm_11: I think it was ambiguous in the spec | 19:27 |
| dansmith | #2 is certainly what I was thinking when I agreed to the spec | 19:27 |
| mriedem | melwitt: hmm, seems that parsing the output of nova commands in the functional tests is going to be..."fun" | 19:27 |
| dansmith | vilobhmm_11: so before we re-propose for liberty we should get clarification on that | 19:27 |
| dansmith | vilobhmm_11: have you proposed that re-approval for mitaka yet? | 19:28 |
| melwitt | dansmith, vilobhmm_11: I think there's disagreement about it | 19:28 |
| melwitt | but if the majority wanted #1, then I was okay with that | 19:28 |
| dansmith | melwitt: seems like it, so we should make sure to not fast-track-approve that on the way into mitaka | 19:28 |
| vilobhmm_11 | melwitt : AFAIR majority wanted it to be #1 ….as you clearly mentioned above | 19:29 |
| dansmith | vilobhmm_11: I remember the opposite :) | 19:29 |

| melwitt | dansmith: I thought jaypipes and johnthetubaguy were agreeing on #1 | 19:31 |
| dansmith | melwitt: I dunno about jaypipes but I thought johnthetubaguy was in favor of #2 | 19:31 |
| melwitt | mriedem: yeah. it's worth noting we have a guideline that it's okay to use the python api for the setup steps, which should help | 19:32 |
| mriedem | melwitt: this is to assert the output | 19:32 |
| mriedem | table either has a column or doesn't | 19:32 |
| mriedem | based on microversion | 19:32 |
| melwitt | oh | 19:32 |
| bauzas | melwitt: I thought the consensus was for #2 | 19:32 |
| mriedem | _get_value_from_the_table doesn't really work | 19:32 |
| dansmith | vilobhmm_11: let me ask you a question... zk can expose arbitrary attributes for a service, right? | 19:32 |
| melwitt | so... I guess there is some confusion here | 19:32 |
| vilobhmm_11 | melwitt : +1 that jaypipes and johnthetybaguy ageed on #1 and so did everyone who gave +1 IMHO | 19:33 |
| vilobhmm_11 | dansmith : yes | 19:33 |
| bauzas | mmm | 19:33 |
| bauzas | vilobhmm_11: is this written somewhere? ideally in the spec ? | 19:33 |
| vilobhmm_11 | dansmith : i have proposed https://review.openstack.org/#/c/221947/ to make it happen in tooz | 19:33 |
| *** pumaranikar has joined #openstack-nova | 19:33 | |
| *** thangp_ has joined #openstack-nova | 19:34 | |
| vilobhmm_11 | dansmith : does that answer you question ? | 19:34 |
| dansmith | vilobhmm_11: meaning zk can do it but tooz doesn't support it yet? | 19:34 |
| vilobhmm_11 | tooz can expose service deatils as a blob | 19:34 |
| *** thangp has quit IRC | 19:34 | |
| vilobhmm_11 | https://github.com/openstack/tooz/blob/master/tooz/drivers/zookeeper.py#L273 | 19:35 |
| vilobhmm_11 | my change gets details about the znode | 19:35 |
| dansmith | vilobhmm_11: okay, so we have a number we associate with a service now, | 19:35 |
| vilobhmm_11 | znode = { znode stats + blob } this blob can be service data | 19:35 |
| dansmith | vilobhmm_11: and we need to calculate the min and max versions of those numbers quite a bit | 19:35 |
| vilobhmm_11 | dabsmith : that needs to go away | 19:35 |
| *** e0ne has quit IRC | 19:35 | |
| vilobhmm_11 | dansmith : ^^ | 19:36 |
| dansmith | vilobhmm_11: for the database driver, we can just select min() and select max() and get that information very efficiently | 19:36 |
| vilobhmm_11 | otherbackends won;t understand that number "id" | 19:36 |
| dansmith | vilobhmm_11: will zk type drivers have to enumerate every service in the deployment and manually iterate all that data to do the calculation? | 19:36 |
| *** sudipto has quit IRC | 19:36 | |
| vilobhmm_11 | dansmith : nope | 19:36 |
| dansmith | vilobhmm_11: okay, so how do we query for that min and max? | 19:37 |
| vilobhmm_11 | if we specify 'topic' , 'binary' , 'host' or a combination of it | 19:37 |
| vilobhmm_11 | we can extract the valid znode from zookeeper | 19:37 |
| dansmith | right, that's not what I'm asking though | 19:37 |
| *** Apoorva has joined #openstack-nova | 19:37 | |
| vilobhmm_11 | dansmith : can you point me to the code which does that ? I should have an answer | 19:37 |
| dansmith | I'm saying we need to find out the minimum and maximum versions of this arbitrary integer attribute | 19:37 |

| *** thangp_ has quit IRC | 19:38 | |
| vilobhmm_11 | dansmith : does this API exist in the code yet ? I mean master and what will this be used for ? | 19:39 |
| dansmith | vilobhmm_11: no, it's proposed, waiting for mitaka | 19:39 |
| vilobhmm_11 | ok | 19:39 |
| dansmith | vilobhmm_11: we need to use this for lots of upgrade-related things | 19:39 |
| vilobhmm_11 | object versioning | 19:39 |
| vilobhmm_11 | ok | 19:39 |
| dansmith | and every node in the cluster will need to be able to calculate min/max | 19:39 |
| *** achanda_ has joined #openstack-nova | 19:40 | |
| dansmith | vilobhmm_11: now, if you maintain service records in the DB and only use zk for liveness, then this is easy | 19:40 |
| dansmith | if we don't do that, how would you do this efficiently? | 19:40 |
| *** achanda has quit IRC | 19:40 | |
| bauzas | I don't really get the benefits of storing the service info within specific driver implementation ? | 19:41 |
| vilobhmm_11 | dansmith : I was not aware this feature is coming in mitaka…I will need to think if this can be done efficiently by storing values/data in znodes..can I get back to you by tommorow ? | 19:42 |
| vilobhmm_11 | i agree min/max won't be as fast as its done in db | 19:43 |
| dansmith | vilobhmm_11: sure | 19:43 |
| vilobhmm_11 | dansmith : we should have a clear set of API's which we want to fetch details from backends and others which should fetch from DB | 19:44 |
| vilobhmm_11 | irrespective of the above question that you have asked | 19:44 |
| dansmith | vilobhmm_11: right like "liveness" and "anything else" right? :) | 19:44 |
| *** dave-mccowan has quit IRC | 19:45 | |
| vilobhmm_11 | dansmith : liveliness agree..but need to clear on this "anything else" part though :) | 19:46 |
| dansmith | vilobhmm_11: "anything else" is "everything we have now" and also "things in the future that are not related to liveness" :) | 19:47 |
| *** dave-mccowan has joined #openstack-nova | 19:50 | |
| *** lpetrut has quit IRC | 19:50 | |
| vilobhmm_11 | dansmith : sure…by tommorow should have a clear list of API;s that should go under "liveliness" vs ""everything we have now except liveliness" …so that all of us ( jaypipes, johnthetubeguy, melwitt, dansmith, vilobhmm_11 ) are on same page | 19:51 |
| dansmith | s/a clear list/a clear list to propose" ... but sure :) | 19:51 |

| tsekiyama | hemna: pong | 20:31 |
| hemna | tsekiyama, hey, so I read your comment on the encrypted vol issue | 20:31 |
| hemna | it's not entirely clear that this is only a case for looking for an 'old' encrypted volume path though. | 20:31 |
| hemna | because it's pulling the value directly from the connection_info, which I presume is coming from the result of the libvirt driver's attach volume call | 20:32 |
| hemna | in which case, for FC devices that device_path may contain an entry pointing to /dev/disk/by-id/dm-uuid-mpath-<WWN> | 20:32 |
| *** pumaranikar has quit IRC | 20:33 | |
| tsekiyama | hemna: yah, it's based on unpatched code I admit it's quite confusing.. | 20:33 |
| tsekiyama | hemna: In that case, /dev/mapper/dm-uuid-mpath-<WWN> will be the name of crypt device in old code | 20:34 |
| *** pumaranikar has joined #openstack-nova | 20:34 | |
| hemna | so I think your old_dev_name in that case will end up being dm-uuid-mpath-<WWN> which it won't find in /dev/mapper | 20:34 |
| tsekiyama | hemna: so the patch is trying to check whether the crypt device is there or not | 20:34 |
| hemna | if it's a multipath device the /dev/mapper entry will be /dev/mapper/<WWN> | 20:35 |
| *** dustins has quit IRC | 20:35 | |
| tsekiyama | hemna: right | 20:36 |
| hemna | in which case the new name of crypt-dm-uuid-mpath-<WWN> will fail | 20:36 |
| hemna | :( | 20:36 |
| *** ndipanov has quit IRC | 20:37 | |
| hemna | shouldn't it be based off of the WWN ? | 20:37 |
| hemna | which can be obtained w/ a call to scsi_id --page 0x83 --whitelisted <device> | 20:37 |
| tsekiyama | hemna: do you mean multipath case or not? | 20:38 |
| hemna | but I think that will always be found as /dev/mapper/<WWN> | 20:38 |
| hemna | multipath case | 20:38 |
| hemna | if the daemon is running and it creates a mpath device you'll get /dev/mapper/<WWN> as a valid mpath device. | 20:39 |
| tsekiyama | In multipath case, device_path will be /dev/mapper/<WWN>, right? | 20:39 |
| hemna | yah | 20:39 |
| hemna | but you don't have a search for <WWN> | 20:40 |
| hemna | the search will be looking for /dev/mapper/dm-uuid-mpath-<WWN> | 20:40 |
| hemna | which won't be there :) | 20:40 |
| *** lucas-dinner has quit IRC | 20:40 | |
| tsekiyama | As far as I tested, if multipath is enabled, connection_info['data']['device_path'] is '/dev/mapper/<WWN>', which is pointing dm-multipath device. | 20:41 |
| hemna | for iSCSI yes | 20:41 |
| hemna | not for FC | 20:41 |
| tsekiyama | ah | 20:41 |
| hemna | and I have plans on updating the discovery code in os-brick iSCSI to match the FC discovery code | 20:42 |
| hemna | because calling multipath -ll to discover the device is horribly slow on some systems. | 20:42 |
| tsekiyama | hmm ok | 20:42 |
| hemna | tsekiyama, re: https://goo.gl/Xqx1Tx | 20:43 |
| hemna | tsekiyama, that patch explains the new discovery model and what paths might show up for FC related volumes. and during M, I'll update the iSCSI discovery code to do the same. | 20:44 |
| hemna | it's on my TODO list | 20:44 |
| *** otter768 has joined #openstack-nova | 20:44 | |
| *** mwagner_lap has quit IRC | 20:44 | |
| hemna | tsekiyama, I wonder if it's of value to return the volume WWN as part of os-brick's connect_volume call along w/ the device_path, etc | 20:45 |
| hemna | then you could just read the WWN and go | 20:45 |
| hemna | other connectors (NFS, ceph, etc) might not be able to get that WWN though. | 20:46 |
| tsekiyama | hmm, I think I got the point. I'll check the code for details. | 20:46 |

| dansmith | bauzas: cool :) | 21:24 |
| bauzas | dansmith: just commented | 21:24 |
| bauzas | dansmith: here, we could have operators who would like to have a behaviour where they would have to upgrade a service before putting it back in rotation | 21:25 |
| bauzas | because of some ITIL change window or etc. | 21:25 |
| bauzas | and not wait to have all the computes being up | 21:25 |
| bauzas | oh wait | 21:26 |
| bauzas | that's possible just by leaving the RPC pin | 21:26 |
| bauzas | and not use 'auto' | 21:26 |
| *** boris-42 has joined #openstack-nova | 21:26 | |
| bauzas | I mean, operators can do whatever they want by using the rpc versions flag we just need to think about the default UX | 21:27 |
| dansmith | bauzas: my second patch will bail if you try to start up a service that is too old, yeah | 21:27 |
| bauzas | but a service can be up but disabled | 21:28 |
| dansmith | ...yeah | 21:29 |

| *** dave-mccowan has joined #openstack-nova | 21:30 | |
| bauzas | I mean, I see your idea | 21:31 |
| bauzas | the new 'auto' option could be not used if the operator would prefer to have a specific version pin | 21:31 |
| mriedem | melwitt: i'm happy to announce today is my first time running novaclient functional tests locally :) | 21:31 |
| mriedem | i'm not ashamed to admit that | 21:31 |
| dansmith | bauzas: correct | 21:32 |
| dansmith | bauzas: but ideally we'd get away from even having the option eventually | 21:32 |
| bauzas | dansmith: I just need to consider whether the default auto behaviour should be accepting disabled or force_down services | 21:33 |
| dansmith | not disabled, but maybe force_down, IMHO | 21:33 |
| bauzas | (again, not speaking of down services, your point is valid about flapping services) | 21:33 |
