#openstack-nova - 2019-09-06
14:39:43 openstackgerrit Matt Riedemann proposed openstack/nova master: Fix incorrect invocation of openstacksdk's baremetal.nodes() https://review.opendev.org/680684
14:39:51 mriedem dtantsur: +2 now ^
14:39:52 mriedem efried: ^
14:39:53 dansmith artom: the source calls the new drop-claim against the dest right?
14:40:02 artom dansmith, yeah
14:40:04 artom So if the dest sets the flag in migrate_data, these things could happen on the source:
14:40:09 dansmith artom: that's what I mean by inbound 5.3
14:40:32 dansmith anyway, yeah I think that's okay
14:41:11 mriedem aspiers: error messages in the api aren't a contract
14:41:20 mriedem only error codes like placement uses, but nova doesn't
14:42:00 mriedem dansmith: yeah basically remove the numa_live_migration flag that goes from dest to source and instead put that as an attribute in migrate_data instead
14:42:01 efried dustinc: I'm merging https://review.opendev.org/#/c/680684/ but please have a look at it when you get in.
14:42:03 mriedem for consistency
14:42:04 artom dansmith, right, dest needs to receive 5.3
14:42:12 artom But nothing needs to actually send it
14:42:15 aspiers mriedem: OK thanks, so I'll just check for HTTPBadRequest and leave it there
14:42:19 efried mriedem, dtantsur: +A
14:42:23 artom So if it sets the flag in migrate_data, we know it's the new code that can receive 5.3
14:42:26 artom And then on the source:
14:42:37 artom Either it's old code and that flag gets dropped by the conductor
14:42:47 dansmith mriedem: right I was just confirming how we calculate that because right now the flag making it through the dest's rpcapi to the source is the sentinel
14:43:06 artom Either it's new code but pinned, in which case the can_send check will fail
14:43:15 artom Or it's new code unpinned, and we proceed with the NUMA LM
14:44:03 mriedem dansmith: yup
14:44:59 mriedem i didn't want to start a pattern of putting random feature flags on those compute rpc api methods, like sev=True, vpmems=True, suchandsuch=True
14:45:56 dansmith mriedem: yeah, but we needed it to figure out if the dest could *send* 5.3, but that's actually not a thing we need to know
14:46:11 dansmith and now we have that can-do method to tell us without actually trying to make the call
14:46:34 artom dansmith, that's the thing, I don't think dest actually needs to send 5.3
14:46:42 artom The changes are all in objects
14:46:45 artom From its POV
14:48:07 dansmith artom: no it doesn't, I'm agreeing
14:48:31 dansmith artom: I think we just kinda munged the "does it support" with "is it configured to allow sending" ... 5.3 when we first discussed it
14:48:40 artom dansmith, yep
14:48:54 dansmith if we were adding new calls on both sides, they'd both need to be configured for 5.3, but in this case, we can cheat
14:50:56 artom dansmith, ack, looks like we're all on the same page, I'll continue down that route and with the rest of mriedem's feedback after the bug call
14:51:07 dansmith cool
14:52:26 mriedem stephenfin: alex_xu: yonglihe: on that topology cli change, this is wrong, correct? https://review.opendev.org/#/c/670790/7/doc/source/cli/nova.rst@3663
14:53:04 mriedem compute:server:topology:host:index is admin-only by default and used to expose host fields
14:54:12 mriedem https://review.opendev.org/#/c/621476/62/nova/api/openstack/compute/server_topology.py@58
14:54:14 mriedem yeah looks like it
14:56:17 donnyd sean-k-mooney: looks like we are still getting a node failure
14:58:06 stephenfin looking
14:59:55 openstackgerrit Balazs Gibizer proposed openstack/nova master: Add min service level check for migrate with bandwidth https://review.opendev.org/680394
15:01:13 stephenfin mriedem: Yup, good catch
15:01:14 mriedem efried: i'm +2 on the other ironic fix https://review.opendev.org/#/c/680542/ but we can wait until the test patch passes https://review.opendev.org/#/c/680643/ - given the state of the gate that might be sometime this weekend though, so maybe you want to +2 and one of us can approve once we have results?
15:01:58 sean-k-mooney donnyd: it might be because its requesting two vms getting one and timeing out getting the second?
15:02:47 mriedem actually that ironic patch already got test nodes, it must be nice to not be nova
15:02:49 efried mriedem: I was thinking along the same lines. But iiuc dtantsur followed up later and said the grenade fix wasn't actually related to this bug. We (still) don't have CI coverage that will hit it. I just proposed https://review.opendev.org/680718 in tripleo which will hopefully hit the job that originally uncovered the problem.
15:02:58 openstackgerrit Balazs Gibizer proposed openstack/nova master: migrate: Add bw min service level check of source compute https://review.opendev.org/680395
15:03:06 efried s/grenade fix/grenade failure/
15:03:38 mriedem alright then
15:03:40 mriedem moving on
15:04:05 sean-k-mooney donnyd: ill check it at the weekend agian when the ci does not have as high a load
15:04:05 efried mriedem: but given how simple and obviously-right the fix is, and that dtantsur says it is legit, I think we might want to merge it anyway.
15:04:13 dtantsur efried: I'd make your tripleo patch depending on both fixes. I'm not sure which one of them is most breaking.
15:04:22 mriedem efried: i'm good with that
15:04:34 mriedem i definitely trust dtantsur here and these are simple fixes
15:04:39 efried dtantsur: the symptoms would be different
15:06:00 dtantsur okie
15:06:00 openstackgerrit Balazs Gibizer proposed openstack/nova master: resize: Add bw min service level check of source compute https://review.opendev.org/680396
15:08:32 efried dtantsur, mriedem: +A
15:08:53 dtantsur now let's see if you'll regret trusting me :D
15:09:01 openstackgerrit Balazs Gibizer proposed openstack/nova master: prepare func test env for moving servers with bandwidth https://review.opendev.org/655109
15:09:18 efried It's not clear that the tripleo patch will work as is; I don't understand the job chain that would get us there, or whether nova needs to be added to required_projects *somewhere* (but where??). So it may take a few iterations to figure that out.
15:10:43 mriedem dtantsur: please don't break my achy breaky heart
15:11:13 dtantsur okay
15:11:21 mriedem i'm assuming you get early 90s billy ray cyrus references of course
15:11:58 openstackgerrit Balazs Gibizer proposed openstack/nova master: Func test for migrate server with ports having resource request https://review.opendev.org/655113

15:18:57 gibi mriedem, bauzas: the next 5 patches in the bw series is up-to-date. first patch: https://review.opendev.org/#/c/680394/ last up-to-date patch: https://review.opendev.org/#/c/655113
15:19:09 mriedem gibi: yup, on my list for today
15:20:53 gibi mriedem: thanks. I still have to work on comments in th second half of the patch series and also need to do a follow up for the already merged https://review.opendev.org/#/c/656422
15:21:00 openstackgerrit Balazs Gibizer proposed openstack/nova master: Func test for migrate re-schedule with bandwidth https://review.opendev.org/676972
15:24:03 openstackgerrit Balazs Gibizer proposed openstack/nova master: Support migrating SRIOV port with bandwidth https://review.opendev.org/676980
15:25:11 mriedem stephenfin: is it not possible to deprecate an entire group of config options?
15:25:15 mriedem you have to do them all individually?
15:25:40 stephenfin you can deprecate opts but not groups, afaik
15:25:41 stephenfin so no
15:25:44 mriedem blast
15:25:49 stephenfin soz
15:26:12 mriedem is that hipster millenial for sorry?
15:26:31 mriedem i had to look up what a "stan" was last night
15:26:38 stephenfin let's say...yes
15:26:45 cdent you'll be cool, eventually, mriedem
15:26:54 cdent each day, get better and better

15:41:48 dansmith hoo boy
15:42:01 mriedem i'll post to the ML
15:42:12 stephenfin Ima +2 that so hard.
15:42:19 stephenfin after the ML post, of course
15:46:25 mriedem http://lists.openstack.org/pipermail/openstack-discuss/2019-September/009180.html
15:47:37 mriedem stephenfin: since you smelled it, maybe you should deal up an etherpad for rc todo stuff like the prelude reno
