| mriedem | Kevin_Zheng: https://review.openstack.org/#/c/510235/ ? yeah, it's a very rough work in progress | 01:25 |
| mriedem | ideally i'd get some operator feedback before revising it | 01:25 |
| mriedem | not really pushing to get that in for rocky | 01:26 |
| Kevin_Zheng | OK, maybe we will take it over togother with the dettach root volume for next cycle | 01:26 |
| mriedem | i think it's arguably also a bug fix / security hardening opportunity | 01:26 |

| jangutter | sahid: Thanks for taking a look at https://review.openstack.org/567148 . I agree that there's "duplicate" info passed through for VIFHostDevice, but at least it's consistent with other VIF's. I think it has to do with the distinction between the VIF objects and the VIFPortProfile objects. | 09:29 |
| jangutter | sahid: The os-vif VIF describes "how to wire it into the VM". The os-vif port-profile describes "how to wire it into the datapath". Because the distinction is not particularly clear with libvirt, there's some muddy overlap. | 09:31 |

| mdbooth | kashyap: I'm looking at the libvirt logs from this multiattach job: http://logs.openstack.org/58/567258/5/check/nova-multiattach/d23fad8/logs/libvirt/libvirtd.txt.gz | 09:46 |
| mdbooth | Specifically I'm trying to see what goes on during the successful multiattach swap volume test | 09:47 |
| * kashyap clicks | 09:48 | |
| mdbooth | It looks like the drive of interest is added around 2018-06-04 10:56:57.865+0000 | 09:49 |
| kashyap | Can you tell the drive ID? | 09:49 |
| kashyap | Is it? 'drive-virtio-disk1' | 09:50 |
| mdbooth | drive-virtio-1 | 09:50 |
| *** bigdogstl has joined #openstack-nova | 09:50 | |
| mdbooth | I'm slightly confused, because I don't see shared in the 'human-monitor-command' | 09:50 |
| kashyap | I don't see a "drive-virtio-1". Did you mean: 'drive-virtio-disk1'? | 09:51 |
| mdbooth | But there is "share-rw":"on" in what seems to be sent to qemu | 09:51 |
| mdbooth | kashyap: Yeah | 09:51 |
| kashyap | libvirt uses QMP (the JSON RPC) with QEMU. Not HMP. (only rarely) | 09:51 |

| *** armaan has quit IRC | 09:52 | |
| mdbooth | Right, so that's 'shared', right? | 09:52 |
| kashyap | mdbooth: Yes. And libvirt will _not_ migrate it. | 09:52 |
| mdbooth | i.e. it's multiattach | 09:52 |
| kashyap | Here is the libvirt source itself saying as such: | 09:52 |
| kashyap | 288 /* Default is to migrate only non-shared non-readonly disks | 09:52 |
| kashyap | 289 * with source */ | 09:52 |
| kashyap | 290 return !disk->src->shared && !disk->src->readonly && | 09:52 |
| kashyap | 291 !virStorageSourceIsEmpty(disk->src); | 09:52 |
| kashyap | 292 } | 09:52 |
| kashyap | 293 | 09:52 |
| *** armaan has joined #openstack-nova | 09:52 | |
| mdbooth | kashyap: Except that it does | 09:52 |
| *** antosh has joined #openstack-nova | 09:53 | |
| mdbooth | Keep searching down on that disk id | 09:53 |
| *** andreas_s has quit IRC | 09:53 | |
| mdbooth | 2018-06-04 10:57:05.201+0000 | 09:53 |
| mdbooth | It does a drive mirror | 09:53 |
| *** ispp has joined #openstack-nova | 09:53 | |
| *** andreas_s has joined #openstack-nova | 09:54 | |
| mdbooth | This isn't live migration, btw | 09:54 |
| *** heyongli has quit IRC | 09:54 | |
| mdbooth | This is volume migration | 09:54 |
| *** heyongli has joined #openstack-nova | 09:54 | |
| mdbooth | So the data in volume a is moved to volume b and a is seamlessly substituted for b in the domain | 09:54 |
| *** bigdogstl has quit IRC | 09:54 | |
| *** ispp has quit IRC | 09:55 | |
| kashyap | mdbooth: Hang on -- | 09:55 |
| mdbooth | So it looks like this version of qemu/libvirt at least does permit drive mirror of a shared disk | 09:55 |

| * kashyap looks closer | 09:57 | |
| pvc | hi | 09:58 |
| kashyap | mdbooth: So libvirt should _not_ forbid because, the said shared disk might be in use at any given point. | 09:59 |
| kashyap | But probably that's what you were trying to tell me. | 09:59 |
| mdbooth | kashyap: Actually I think it *should* forbid it, but doesn't | 10:00 |
| pvc | kashyap | 10:00 |
| pvc | can help me with gpu instnace? | 10:00 |
| kashyap | mdbooth: libvirt developer says the above reason is why it shouldn't forbid it | 10:00 |
| mdbooth | Although... meh it should probably give us the rope to hang ourselves with | 10:00 |
| kashyap | pvc: Hi, in the middle of something. Please ask such questions to the operators list or ask.openstack.org | 10:00 |

| kashyap | mdbooth: BTW, yes. I did see the timestamp you pointed out. And indeed the shared disk is being `drive-mirror`ed: | 10:02 |

| kashyap | mdbooth: The shared disk might be in use by the other VM | 10:02 |
| *** myrat has joined #openstack-nova | 10:03 | |
| mdbooth | Exactly, and iiuc libvirt/qemu has no way to know if this is the case | 10:03 |
| mdbooth | So doing a drive mirror isn't a safe operation, because it can't take account of changes made by another vm | 10:03 |
| kashyap | (Hmm, the libvirt dev isn't sure if QEMU disallows forbids or not.) | 10:04 |
| mdbooth | You'd need a side-channel between all attached vms to make that safe. | 10:04 |
| *** heyongli has quit IRC | 10:04 | |
| mdbooth | And you can't do it in the guest os, because this operation isn't visible to the guest os | 10:04 |

| mdbooth | kashyap: Which channel are you on? | 10:05 |
| kashyap | #virt, OFTC | 10:05 |
| mdbooth | kashyap: I'm not convinced it's a bug, tbh. | 10:05 |
| *** shaohe_feng has quit IRC | 10:06 | |
| mdbooth | Well actually I do think it's a bug, but in Nova. | 10:06 |
| mdbooth | I don't think we should be attempting to do this in the first place. | 10:06 |

| *** shaohe_feng has joined #openstack-nova | 10:06 | |
| *** armaan has quit IRC | 10:07 | |
| mdbooth | The problem with that is that to fix it we have to break an api | 10:07 |
| *** armaan has joined #openstack-nova | 10:07 | |
| mdbooth | i.e. make something fail which previously succeeded | 10:07 |

| kashyap | mdbooth: So, the _default_ behaviour for libvirt is that it won't migrate the shared disks if you don't ask for them to be shared. | 10:20 |
| kashyap | If you _do_ aske the shared disks to be migrated, libvirt will honor that. | 10:20 |
| kashyap | I think Nova shouldn't do that is what you are saying. | 10:21 |
| *** annp has quit IRC | 10:21 | |
| lyarwood | kashyap: volume migration in this context is swap volume, so rebasing in libvirt terms. | 10:21 |
| kashyap | Yep. blockRebase()/blockCopy() --> calls QEMU 'drive-mirror' | 10:21 |
| lyarwood | kashyap: right, just checking you didn't have it confused with actual block LM. | 10:22 |
| kashyap | Yeah, my head already auto-maps _swap_volume() to the above APIs. But thank you :-) | 10:23 |
| kashyap | lyarwood: Actual block LM also goes down to that 'drive-mirror' call, you know that? | 10:23 |
| lyarwood | kashyap: yeah without going through blockRebase right? | 10:24 |
| lyarwood | kashyap: it's just a copy | 10:24 |

| *** pchavva has joined #openstack-nova | 13:04 | |
| mriedem | lyarwood: i don't really have a great way to test this stuff until i get the stack written through the compute api, so i figure any issues that are on the cinder side with modeling per-attachment access mode will have to be resolved as dependent bugs | 13:04 |
| artom | mdbooth, so, re: mailing list post about swap volume - I believe we could just change the response code in the multi-attach case to a 400 or 409 or whatever, without a new microversion | 13:05 |
| artom | https://docs.openstack.org/nova/latest/contributor/microversions.html | 13:05 |
| mriedem | lyarwood: beyond that, what is holding up the spec? i'll rename attach_mode to access_mode to match what's in the connection_info | 13:05 |
| mdbooth | artom: I wasn't sure, but that was my intention. I don't think we should preserve this behaviour at all, even behind a microversion. | 13:06 |
| mdbooth | artom: But I'm not clear on the policy here, hence the ML post. | 13:06 |

| jangutter | sahid: yep, but in https://github.com/openstack/nova/blob/stable/queens/nova/network/os_vif_util.py#L287-L297 it's used, and in https://github.com/openstack/nova/blob/stable/queens/nova/network/os_vif_util.py#L329-L347 the apparent redundancy is explained (poorly, by me) | 13:41 |

| mriedem | dansmith: and looking back, i'm still not sure why we didn't have a new metadata api version for that since it was adding a new key to the response | 13:41 |
| mriedem | we'd never let that fly in the compute rest api | 13:41 |
| mriedem | but metadata api is the wild west pew pew | 13:42 |
| * jaypipes gets his revolver. | 13:42 | |
| dansmith | well, probably because it's a fairly small iteration | 13:42 |
| *** shaohe_feng has joined #openstack-nova | 13:42 | |
| dansmith | and because of how metadata is | 13:42 |
| dansmith | but yeah | 13:42 |
| mriedem | sahid: +2 on https://review.openstack.org/#/c/553072/ now | 13:42 |
| dansmith | mriedem: so I haven't looked at this spec in the past, but has someone gone through and looked at what the delta looks like from the existing? | 13:42 |
| sahid | mriedem: ok cool | 13:43 |
| dansmith | or is it just that we only ever populate networks[0] now? | 13:43 |
| mriedem | dansmith: it adds a new ip_addresses field to the response which is a list of fixed ips rather than the first one from the list | 13:43 |
| mriedem | we only take the first fixed ip today | 13:43 |
| mriedem | which is the ip_address field | 13:43 |
| sahid | jangutter: hum... i don't understand the note | 13:43 |
| mriedem | this exposes the list of fixed ips | 13:43 |
| mriedem | and still maintains the single ip_address field - which arguably we don't need to do since it's versioned | 13:44 |
| mriedem | i don't know how sensitive apps are to doing version discovery with metadata | 13:44 |
| dansmith | mriedem: this certainly looks like we're asserting multiple interfaces and ips in the test no? https://github.com/openstack/nova/blob/4b333b989dfc778a8b61db4a1b8552e988a10471/nova/tests/unit/network/test_network_info.py | 13:44 |

| *** tbachman has joined #openstack-nova | 13:45 | |
| mriedem | that's a single ipv4 fixed ip | 13:45 |
| mriedem | but you can have multiple fixed ips per port in neutron | 13:45 |
| mriedem | which is what this spec is trying to expose via network_data.json | 13:45 |
| dansmith | oh, | 13:46 |
| dansmith | I thought the spec was saying it was the subsequent networks and the ips there that it needed to add | 13:46 |
| jangutter | sahid: Back in the day, when I wrote that, my rationale was something like: the VIF is used to generate the xml for libvirt, the port_profile is used to find the representor and plug it into the bridge. | 13:46 |
| *** nmathew has quit IRC | 13:46 | |
| mriedem | there is also something in the spec about multiple subnet routes which i didn't fully follow | 13:46 |
| mriedem | i believe the networks list is per-vif (port) | 13:46 |
| dansmith | I see, multiple fixed per port | 13:46 |
| dansmith | is what they're enabling | 13:47 |
| mriedem | similar to how the server "addresses" field works in the compute api | 13:47 |
| mriedem | dansmith: yeah | 13:47 |
| dansmith | sorry, I just skimmed when you sent and haven't really read it | 13:47 |
| mriedem | so you didn't see the dan smith easter egg in there yet | 13:47 |
| jangutter | sahid: Also, the symmetry will break either way, there's only so far you can take the abstraction, I'm agnostic on this, but if the pattern is continued, then at least the os-vif plugins look similar. | 13:48 |
| dansmith | mriedem: well now I can't approve until I find something I think qualifies | 13:49 |

| *** heyongli has quit IRC | 14:10 | |
| jaypipes | mdbooth: my annoyance is that this is a libvirt/QEMU-specific behaviour/implementation that is leaking out of the Compute API. | 14:10 |
| *** heyongli has joined #openstack-nova | 14:10 | |
| kashyap | jaypipes: By _default_ libvirt doesn't copy shared disks | 14:10 |
| mdbooth | jaypipes: That was the thrust of my reply. It's not libvirt/qemu specific at all. | 14:11 |
| jaypipes | mdbooth: BTW, where exactly does "swap volume" imply or denote that there is a copy operation going on? :( | 14:11 |
| kashyap | But if you _ask_ for it, it will migrate it | 14:11 |
| mriedem | mdbooth: the only virt driver that implements this is libvirt | 14:11 |
| *** felipemonteiro_ has joined #openstack-nova | 14:11 | |
| mdbooth | jaypipes: It could be implemented by any hypervisor, and they'd have to do the copy. | 14:11 |
| jaypipes | mdbooth: yes, it is. | 14:11 |
| mriedem | same with guest-assisted volume snapshot | 14:11 |
| mdbooth | jaypipes: I replied in depth on the ML, anyway. | 14:11 |
| jaypipes | yes, I read your reply. | 14:11 |
| mriedem | i have no idea how non-libvirt drivers handle volume retype/live migration either | 14:11 |
| *** shaohe_feng has quit IRC | 14:12 | |
| jaypipes | mriedem: they don't. wisely. | 14:12 |
| *** dpawlik has quit IRC | 14:12 | |
| mdbooth | But Cinder can't do this, regardless of which hypervisor is attached. | 14:12 |
| jaypipes | mdbooth: it's the "live" part that Cinder can't do, yes? | 14:12 |
| mriedem | i must be missing something but i don't see any reply to jaypipes from mdbooth in the ML | 14:12 |
| mdbooth | jaypipes: No, that's just an optimisation. | 14:12 |
| mdbooth | jaypipes: If anything is attached, Cinder needs to ask Nova for help. | 14:12 |
| mdbooth | Nova could just pause, copy, unpause | 14:12 |
| kashyap | jaypipes: To your "swap volume" denoting copy operation, you wouldn't know it, unless you look at the Nova _swap_volume() method | 14:12 |
| jaypipes | mdbooth: then I don't understand what is different between the pause VM, volume migrate, start VM. | 14:13 |
| mriedem | i wonder when k8s is going to implement swap volume for cinder to use | 14:13 |
| mriedem | that will be awesome | 14:13 |
| kashyap | jaypipes: And then, map it to libvirt's blockRebase() API, which is called by _swap_volume(). | 14:13 |
| mdbooth | jaypipes: How would you prevent unpause during the volume migrate? | 14:13 |
| jaypipes | kashyap: no... unless you look at the LIBVIRT driver _swap_volume() method. | 14:13 |
| jaypipes | kashyap: which is my point. | 14:13 |
| kashyap | jaypipes: That's what I said :-) | 14:13 |

| jaypipes | mdbooth: it's an administrative action that involves multiple orchestrated pieces. | 14:14 |
| mdbooth | jaypipes: Note that we're redefining swap_volume here, which is a bit out of scope. My concern relates to multiattach. | 14:15 |
| *** felipemonteiro has quit IRC | 14:15 | |
| jaypipes | mdbooth: and just because libvirt/QEMU has some magic foo to do all that orchestration in a (sometimes) live fashion, we've made the Compute API look like the libvirt/QEMU API and embedded expectations of full coordination/orchestration into our API. and that's wrong IMHO. | 14:15 |
| *** MultipleCrashes has joined #openstack-nova | 14:15 | |
| mdbooth | However, there are 2 parts to it. | 14:16 |
| MultipleCrashes | Please have a look at this review and leave a feedback : https://review.openstack.org/#/c/570370/ | 14:16 |
| jaypipes | mdbooth: yes, I understand your concern about multiattach and artom's suggestion of just barfing back a 400 Bad Request when any of the source or dest volumes in the swap operation are multiattach is a perfectly reasonable "solution" to that. | 14:16 |
| mdbooth | If we removed swap volume and implemented this with pause/resume, we would still need an additional api in nova to 'lock' the pause. | 14:16 |
| jaypipes | mdbooth: I'm just annoyed at everything, sorry. | 14:17 |
| mdbooth | Otherwise, orchestration or not, a concurrent operation could unpause it. | 14:17 |
| artom | jaypipes, would you like a lawn and some kids to yell at? ;) | 14:17 |
| jaypipes | mdbooth: precisely. which is why it belongs in an orchestration layer, not the virt driver layer :) | 14:17 |
| mdbooth | Also, customers who don't like 6 hours of downtime would be grumpy. | 14:17 |
| jaypipes | artom: :) | 14:17 |
| mdbooth | jaypipes: But you *can't* orchestrate an *inability* for somebody else to do something without a new api. | 14:18 |
| mdbooth | Your orchestrator can pause, migrate, unpause | 14:18 |
| mriedem | mdbooth: so your use case in the ML reply to jay was that people are doing retype to get from old shitty storage to new shiny storage, | 14:18 |
| mriedem | but that's still initiated through cinder's retype API | 14:18 |
| openstackgerrit | Balazs Gibizer proposed openstack/nova master: Send resource allocations in the port binding https://review.openstack.org/569459 | 14:18 |
| mriedem | what's the use case for using the swap volume API directly w/o cinder? | 14:18 |
| mdbooth | But it can't prevent my user, frustrated that his data has been unavailable for 6 hours, from unpausing | 14:18 |
| mdbooth | mriedem: No idea. I don't think it matters here, though. | 14:19 |
| mriedem | i think it matters to understand how people are using or abusing the APIs | 14:20 |
| mriedem | os-server-external-events is a public REST API which i could call directly with admin creds, i don't know why i would, but i can | 14:20 |
| mriedem | doesn't mean i should | 14:20 |
| jaypipes | mriedem: ++ | 14:20 |
| mdbooth | mriedem: Agreed. I don't think it's specific to this case, though. | 14:20 |
| *** heyongli has quit IRC | 14:20 | |
| mdbooth | mriedem: It doesn't impact the multiattach thing. | 14:21 |
| artom | mriedem, I think the difference here is that, calling os-server-external-events doesn't potentially corrupt data | 14:21 |
| *** heyongli has joined #openstack-nova | 14:21 | |
| mriedem | you guys are missing the point | 14:21 |
| jaypipes | mdbooth: BTW, I'm not insinuating that you personally have anything to do with this swap_volume() code. Just pointing out I don't think this particular API call belongs in the compute API. | 14:21 |
| artom | For instance, if we discovered that calling it with a certain event caused a VM to go down (suspend your disbelief, work with me) | 14:21 |
| artom | We'd fix that, regardless of how silly the "use case" (or lack thereof) was | 14:21 |

| artom | mdbooth, I mean, I did? | 14:25 |
| artom | Return a 400? | 14:25 |
| mdbooth | Oh, I think you're saying that the direct call use case is relevant here because it's all that's stopping us from implementing this in cinder? | 14:25 |
| artom | jaypipes seems on board with it | 14:25 |
| mdbooth | In which case, yeah. | 14:25 |
| mriedem | mdbooth: yes | 14:26 |
| mriedem | i would prefer to just put the blocker in cinder | 14:26 |
| mriedem | reasons are in my ML reply | 14:26 |
| mriedem | 1. source of truth so less racy and 2. no rollbacks for retype or live migration for volumes | 14:26 |
| * mdbooth is going to take a few minutes for coffee and ML reading... | 14:26 | |

| smcginnis | I haven't been following the discussion at all, but if we want to block something in cinder, make sure it makes sense for use cases outside of nova. | 14:27 |
| mriedem | and then you better pray that cinder rolls back properly | 14:27 |
| mriedem | smcginnis: you probably missed my k8s snark earlier | 14:27 |
| *** pchavva has quit IRC | 14:27 | |
| artom | mriedem, so we'd have to 1. block it in cinder early on 2. block it in nova for the ludicrous direct-call case | 14:27 |
| mriedem | how would a volume live migratoin / retype work with k8s when k8s doesn't implement a swap volume callback API? | 14:27 |
| mriedem | artom: i guess | 14:27 |
| mriedem | i can hack something up for the nova side blocker | 14:27 |

| bauzas | dansmith: in general, we said a couple of times to operators to randomize more the computes by using host_subset_size or shuffle_best_same_weighed_hosts | 15:21 |
| bauzas | dansmith: so that a new instance was asking for a separate compute | 15:21 |
| *** ttsiouts has quit IRC | 15:21 | |
| dansmith | yeah, but people that want strict packing might not want that | 15:21 |
| bauzas | dansmith: agreed | 15:21 |
| jaypipes | efried: done. | 15:21 |
| bauzas | asking to pack is a problem | 15:21 |
| efried | jaypipes: thanks | 15:21 |
| bauzas | dansmith: what I was more thinking was maybe to deprecate one of the two options I mentioned | 15:22 |
| *** heyongli has quit IRC | 15:22 | |
| bauzas | dansmith: and recommend using your own weigher | 15:22 |
| *** janki has quit IRC | 15:22 | |
| *** heyongli has joined #openstack-nova | 15:22 | |
| bauzas | because once we merge your weigher, we'll get 3 opts for quite the same concern | 15:22 |
| *** ttsiouts has joined #openstack-nova | 15:22 | |
| dansmith | um, why? | 15:23 |
| dansmith | I don't think those overlap | 15:23 |
| bauzas | dansmith: I think shuffle_best_same_weighed_hosts overlaps | 15:23 |
| *** pcaruana has quit IRC | 15:23 | |
| *** shaohe_feng has quit IRC | 15:23 | |
| *** Luzi has quit IRC | 15:23 | |
| dansmith | with my weigher? | 15:24 |
| bauzas | dansmith: it's two different implementations | 15:24 |
| dansmith | I don't get that | 15:24 |
| bauzas | but at the end, we want to make sure we pack correctly | 15:24 |
| dansmith | without this weigher, hosts that have been failing will be considered at the same score as those that haven't.. shuffle just changes the likelihood you'll land on one of those, modulo the subset size | 15:25 |
| dansmith | with my weigher they're likely not in consideration, moving your chance closer to 100% | 15:25 |
| *** tbachman has joined #openstack-nova | 15:25 | |
| bauzas | right, that's my point | 15:26 |
| bauzas | asking to shuffle is just because you want to make sure you go elsewhere | 15:26 |
| dansmith | so, without this weigher, | 15:26 |
| dansmith | lets say your subset size is 3 | 15:26 |
| dansmith | and shuffle is turned on | 15:26 |
| dansmith | if you have a few hosts that are empty, they score high. if one of those is misconfigured, | 15:27 |
| dansmith | your chance of booting is 66% | 15:27 |
| *** r-daneel has joined #openstack-nova | 15:27 | |
| dansmith | with this weigher, you'd get two empty hosts, plus one that has stuff on it in the subset | 15:27 |
| bauzas | right, I'm saying your weigher improves the changes | 15:27 |
| bauzas | chances* | 15:27 |
| * dansmith is so confused | 15:27 | |
| bauzas | that's why I don't see the need for shuffle_best_same_weighed_hosts | 15:28 |
| bauzas | I'm asking to deprecate shuffle_best_same_weighed_hosts | 15:28 |
| *** shaohe_feng has joined #openstack-nova | 15:28 | |
| bauzas | because this option just does a random shuffle | 15:28 |
| dansmith | but, in the absence of failing hosts, shuffle still helps to balance concurrent boot traffic right? | 15:28 |
| dansmith | I don't see shuffle as being used for avoiding faults at all | 15:29 |
| *** rajinir has joined #openstack-nova | 15:29 | |
| *** tbachman has quit IRC | 15:31 | |
| bauzas | maybe my concern is just that I dislike this shuffle option :) | 15:32 |
| *** heyongli has quit IRC | 15:32 | |
| bauzas | if you want to spread on a specific metric, just ask for a weigher using that metric | 15:32 |
| *** heyongli has joined #openstack-nova | 15:32 | |
| bauzas | instead of just hoping you'll get spread for free | 15:32 |

| dansmith | shuffle is purely to avoid super strict packing right? | 15:34 |
| *** shaohe_feng has joined #openstack-nova | 15:34 | |
| dansmith | if you have big computes and small instances, | 15:34 |
| dansmith | you might build 100 instances in the same exact compute before it's completely full and you move onto the next bucket in the line | 15:35 |
| dansmith | shuffle seems good for just saying "we generally want packing, but not suuuuuper strict" | 15:35 |

| efried | stephenfin: https://review.openstack.org/#/c/564440/3/nova/conf/neutron.py | 16:10 |
| mriedem | bauzas: pre_live_migration is an rpc call from the source compute | 16:10 |
| *** hongbin has quit IRC | 16:10 | |
| mriedem | so yes if that fails, the source sets the migration as an error and stops | 16:10 |
| mriedem | bauzas: https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L6077 | 16:11 |
| efried | stephenfin: What I thought I saw there is that you can only have your tunnel provider (singular) associated with one NUMA node. Is that right? | 16:11 |
| stephenfin | efried: Nope | 16:11 |
| stephenfin | I'm using the term tunnel provider but what I really mean is tunnel endpoint | 16:12 |
| bauzas | mriedem: ok, so that will work, because I wasn't seeing any exception coming from the virt layer handled by the dest host | 16:12 |
| *** homeski has quit IRC | 16:12 | |
| stephenfin | namely, the logical NIC where all tunneled traffic ingresses and egresses from the compute node | 16:12 |
| *** homeski has joined #openstack-nova | 16:12 | |
| bauzas | mriedem: the spec is a bit missing of details, but okay | 16:12 |
| stephenfin | logical because it can actually be two or more physical NICs bonded together | 16:12 |
| efried | stephenfin: Ah. And those multiple NICs may live on multiple NUMA nodes. | 16:13 |
| openstackgerrit | Murali Annamneni proposed openstack/nova master: Enables MySQL Cluster Support for Nova https://review.openstack.org/446643 | 16:13 |
| stephenfin | you're only allowed one tunnel endpoint in neutron. Every tunneled network must use that endpoint | 16:13 |
| stephenfin | efried: Correct | 16:13 |
| stephenfin | Ditto for physnet-type networks (e.g. layer 2) | 16:13 |
| *** heyongli has quit IRC | 16:13 | |

| bauzas | mriedem: it's a pure implementation thing | 16:27 |
| bauzas | mriedem: it's just the fact we pass straight to the compute the migrate_data object that we build by the conductor | 16:27 |
| bauzas | or the api | 16:27 |
| stephenfin | efried: You're not on openstack-oslo but https://review.openstack.org/#/c/564822/ | 16:27 |
| mriedem | "you somehow need to hook into this and call the virt driver so that you can raise the exception." | 16:27 |
| mriedem | bauzas: ^ is all over rpc call | 16:27 |
| mriedem | so if the virt driver raises an exception, it goes back to the source and fails | 16:28 |
| bauzas | mriedem: but the source host never touches it *before* the dest compute amends it | 16:28 |
| *** _pewp_ has joined #openstack-nova | 16:28 | |
| stephenfin | efried: I spotted the same issue on oslo.logging (I think) earlier this week | 16:28 |
| mriedem | bauzas: it doesn't need to | 16:28 |
| bauzas | mriedem: sure, but the spec was saying "we pass the source params to the dest so it can fail there" | 16:28 |
| mriedem | the dest host populates that information and sends it back to the source | 16:28 |
| mriedem | bauzas: where does it say that? | 16:29 |

| *** bigdogstl has quit IRC | 17:19 | |
| mgagne | got 3 nova-specs change merged in 1 day. more in 1 day than 2 whole years? /s =) | 17:19 |
| dansmith | heh | 17:19 |
| mriedem | lyarwood: btw, connection_info has access_mode but the volume attachment records in cinder have attach_mode | 17:20 |
| mriedem | so that's probably where i got it | 17:20 |
| mriedem | mgagne: you are now at your quota limit for nova specs | 17:20 |
| mgagne | haha, for the next 2 years, see you at OpenStack Xylophone | 17:21 |
| dansmith | heh | 17:21 |
| mriedem | openstack xenophobe coming to a denver conference center near you! | 17:22 |
| mriedem | lyarwood: so on https://review.openstack.org/#/c/552078/ i'm inclined to leave it attach_mode to mirror what's in the cinder api | 17:22 |
| mriedem | lyarwood: given that, i'm not sure if there is additional stuff you need for that spec | 17:23 |
| mriedem | i also realize i'm talking to a dev/null here and hopefully you'll come out of your FFU dungeon for awhile to reply | 17:23 |

| mriedem | melwitt: not sure if anyone talked to you about this yet, but https://review.openstack.org/#/c/572583/ is likely going to be a major priority to get done in rocky since nested provider stuff is going to be held up on us handling the data migration properly | 21:32 |
| *** shaohe_feng has quit IRC | 21:32 | |
| mriedem | i think we might want to have a call or something to go over relative priorities for things we really need to get done in the 3rd milestone, because i have a feeling there are a few things floating around | 21:32 |
| mriedem | this and handling a down cell are the 2 main ones i'm thinking of | 21:33 |

| melwitt | I'm aware of the importance of the data migration stuff, for whatever reason I didn't realize the "reshape" spec was about that | 21:33 |
| melwitt | yeah, sounds cool to me | 21:34 |
| mriedem | i ignored the whole nrp upgrade thread in the ML, just jumped on the call yesterday that led to the spec | 21:35 |
| mriedem | tl;dr there will be a new placement api to atomically change the inventory and allocations for a given set of providers/consumers, which we'll run on start of a compute when upgrading to rocky, and we'll also have an offline hook to do that also for FFU | 21:35 |

| mriedem | maybe | 21:42 |
| mriedem | i haven't gone through efried's spec in detail yet, and need to go through surya's latest revision | 21:42 |
| *** shaohe_feng has quit IRC | 21:43 | |
| mriedem | friday at least | 21:43 |
| mriedem | once the spec freeze dust settles | 21:43 |
| mriedem | and i'd consider these spec freeze exception candidates | 21:43 |
| *** shaohe_feng has joined #openstack-nova | 21:43 | |
| melwitt | okay, that's what I was about to ask | 21:43 |
| melwitt | if we needed to do all the things by EOD tomorrow or if we have some time as exceptions | 21:44 |
| mriedem | we can always make exceptions | 21:44 |

| dansmith | mriedem: reading the docs for the other weights we have makes me realize we have some that accept negative values | 21:45 |
| *** bigdogstl has quit IRC | 21:45 | |
| dansmith | so maybe I should make the default -BIGNUMBER and require them to use negative values to properly weigh failures | 21:46 |
| artom | mriedem, drive by review on https://review.openstack.org/#/c/572790/, will go to sleep soon (travelling back to my time zone) | 21:46 |
| dansmith | I thought they were all zero/positive | 21:46 |
| mriedem | dansmith: i know there was an iops one that i saw | 21:46 |
| mriedem | that was the only one i saw i guess | 21:46 |
| *** dpawlik has joined #openstack-nova | 21:47 | |

| mriedem | sorry i got artom'ed | 21:50 |
| artom | im in ur patch, artoming ur patch | 21:50 |
| dansmith | ouch | 21:50 |
| mriedem | dansmith: if negative makes more sense then that's fine by me | 21:50 |
| melwitt | dansmith: if none of the other weighers auto-negate things, I would think it's more intuitive if it's specified as a negative number. with the thinking that if the normal pattern is "bigger numbers win" then specifying a larger negative number means weight a failure as far less likely to be selected | 21:51 |
| mriedem | honestly the weight multipliers break my head | 21:51 |
| melwitt | am I thinking about that right? | 21:51 |
| dansmith | well, I dunno | 21:51 |
| dansmith | melwitt: the way I think of all our weighers, the bigger the number, the more significance it has | 21:51 |
| melwitt | I'd want to pick something that fits in best with what's there so that people who already use it don't have to reverse their thinking for that one option | 21:51 |
| dansmith | however, there area few where you may want affinity or the opposite, so you can do negative or positive | 21:51 |
| *** heyongli has quit IRC | 21:51 | |
| melwitt | *already use weights | 21:51 |
| *** dpawlik has quit IRC | 21:51 | |
| dansmith | you likely never want to prefer hosts that suck, | 21:52 |
| *** heyongli has joined #openstack-nova | 21:52 | |
| dansmith | so I dunno that it would ever be positive (if we didn't auto-negate) | 21:52 |
| mriedem | https://github.com/openstack/nova/blob/master/nova/conf/scheduler.py#L428 is the one i noticed | 21:52 |
| mriedem | oh and this https://github.com/openstack/nova/blob/master/nova/conf/scheduler.py#L737 | 21:52 |
| mriedem | weight_of_unavailable... | 21:52 |
| *** shaohe_feng has quit IRC | 21:53 | |
| dansmith | that's a bit different | 21:53 |
| *** bigdogstl has quit IRC | 21:53 | |
| dansmith | and the iops one can be positive or negative with useful meaning | 21:54 |
| melwitt | do the other negative ones ever make sense as positive values? k | 21:54 |
| *** rcernin has joined #openstack-nova | 21:54 | |
| dansmith | yes, ops defaults negative, but changing it to positive means something useful | 21:54 |
| *** shaohe_feng has joined #openstack-nova | 21:54 | |
| dansmith | soft_anti_affinity and soft_affinity are both positive, but have opposite meanings | 21:55 |
| *** artom has quit IRC | 21:55 | |
| dansmith | https://github.com/openstack/nova/blob/master/nova/scheduler/weights/affinity.py#L93-L96 | 21:55 |
| melwitt | so if it auto negates ... to make build fails even less likely to schedule toward, you would increase the positive value. that is, make build failures heavier | 21:55 |
| dansmith | Just like I do ^ | 21:55 |
| dansmith | melwitt: right, if it auto-negates (as it does now) then you raise the number to make build failures more significant (i.e. less likely to be chosen) | 21:56 |
| dansmith | I think that anti-affinity one is my proof that I'm okay | 21:56 |
| melwitt | yeah, that makes sense to me | 21:56 |
| dansmith | it auto-negates because it makes more sense to have a positive value for significance | 21:56 |
| melwitt | yeah it's like a coefficient I guess | 21:56 |
| mriedem | i left a question in there, but should we put a min value on the multiplier? | 21:57 |
| melwitt | I think either way is find, both make sense in their own way | 21:57 |
| mriedem | otherwise anything negative weighs failed hosts higher right? | 21:57 |
| melwitt | *fine | 21:57 |
| dansmith | mriedem: I dunno, if somene wanted to actually select recent fails, they could set it to -BIG, which ... maybe? | 21:57 |
| dansmith | if they do auto-disable on their own, | 21:57 |
| dansmith | they may want recently-fixed hosts to be super important or something? | 21:57 |
| mriedem | via notifications or something | 21:58 |
| melwitt | although allowing negative and positive values could make you favor build failures if you mess up, so maybe that is worse | 21:58 |
| dansmith | I wouldn't document that, but if you remove the ability, then they can't | 21:58 |
| *** tbachman has joined #openstack-nova | 21:58 | |
| mriedem | sure | 21:58 |
| dansmith | melwitt: right but if you do ^ then maybe you want that | 21:58 |
| mriedem | anywho | 21:58 |
| mriedem | watcher could have it's own super awesome auto-disabler | 21:58 |
| dansmith | I think I'm going to leave it as-is, I convinced myself with the anti-affinity precedent | 21:58 |
