07:30:24 openstackgerrit Brin Zhang proposed openstack/nova master: Filter migrations by user_id/project_id https://review.opendev.org/674243
07:50:01 gibi do we have a solution for the gate failure: ERROR: Could not find a version that satisfies the requirement configparser===4.0.1
07:50:04 gibi ?
07:50:24 alex_xu gibi: I saw this https://review.opendev.org/#/c/681630/
07:51:24 alex_xu so it suppose to be work now?
07:52:53 gibi alex_xu: thanks, then I go and recheclk
07:52:55 gibi recheck
08:17:44 lyarwood Have we cut M3 yet? I've been holding off for a while on posting bugfixes to avoid clogging up the gate.
08:18:01 lyarwood wait, the deadline is today, ignore me.
08:18:13 gibi lyarwood: yepp, today is still crazy FF day
08:19:44 lyarwood ack thanks I'll hold off in that case
08:24:59 openstackgerrit Balazs Gibizer proposed openstack/nova master: Make SRIOV computes non symmetric in func test https://review.opendev.org/681667
08:34:11 stephenfin alex_xu: Looking
08:35:30 stephenfin alex_xu: That looks correct. I started work on the fix for that yesterday but haven't finished. It only happens if you have two compute nodes though, right?
08:36:35 alex_xu stephenfin: it can be happened for 100 nodes, if all 100 nodes can get from placement allocation candidtes, but failed in later filtering
08:37:04 stephenfin both cases?
08:37:15 alex_xu stephenfin: yes, see the line 25
08:37:24 alex_xu stephenfin: I think the root cause is that
08:38:29 stephenfin but it'll only happen if we attempt to use the same host
08:38:32 alex_xu I don't think I figure out the root cause yesterday, it isn't just about resize
08:38:46 alex_xu what about case1
08:39:41 alex_xu stephenfin: I think anycase about placement can return candidates, but nova scheduler filter refuse the request.
08:39:54 alex_xu then we won't fallback
08:41:34 stephenfin true
08:41:43 stephenfin hmm
08:42:06 stephenfin I'm still tempted to think it's not a huge issue. You'd need an awful lot to go against you
08:42:09 alex_xu stephenfin: but need to think about that whether we can have such worse case, like 100 nodes failed at filter not the placement
08:42:44 stephenfin Namely that you're in the middle of an upgrade and you've got a lot of failures in the compute node
08:42:59 alex_xu I guess it will bad in the every begining of upgrade, like you only have 5 nodes or 10 nodes in T
08:42:59 stephenfin I'd be tempted to just add a workaround option
08:43:21 stephenfin That, when enabled, will trigger "request VCPU by default"
08:43:45 stephenfin so if someone ran into this in the middle of an upgrade, they'd set the config option and we wouldn't request PCPU until they've a few more compute nodes upgraded
08:43:50 stephenfin It might be overkill thoughj
08:43:52 stephenfin *though
08:43:52 alex_xu ok, the operator can switch that when he confidence he has enough PCPU node
08:43:57 stephenfin yeah
08:44:25 alex_xu stephenfin: I guess someone may say we add more job for operator
08:44:48 alex_xu stephenfin: how deficult if we fallback the whole placment+filtering
08:44:57 stephenfin I'm looking now
08:46:28 alex_xu I'm thinking we don't want to fallback all the time, how to do that check condition when filter failed
08:48:56 stephenfin alex_xu: Okay, I think it should be possible. Leave it with me :)
08:49:17 alex_xu stephenfin: so cool :)
08:50:19 bauzas alex_xu: stephenfin: I looked at your convo, can you please summarize me why the filter would different from placement ?
08:50:36 alex_xu bauzas: here is two cases I found https://etherpad.openstack.org/p/pcpu_fallback
08:50:38 alex_xu maybe more
08:51:02 stephenfin bauzas: We try to get PCPU from placement, and if that returns nothing we try for VCPU
08:51:11 stephenfin It's to minimize the upgrade impact
08:51:41 stephenfin However, if the first request does return some stuff, but those things fail the filters, we don't do the fallback for VCPU
08:51:44 bauzas well, I still don't get it
08:52:09 bauzas that's surely me, but if the operator said "okay, let's go with PCPU", that's because he opted-in, right?
08:52:35 stephenfin they've opted in by setting '[compute] cpu_dedicated_set' on some compute nodes, yes
08:53:08 bauzas but we said that it wouldn't provide PCPU inventories until all computes are opted in, right?
08:53:46 alex_xu bauzas: no, the upgrade plan is changed
08:53:47 bauzas actually, we send new inventories after opting in with the conf opt, you're right
08:53:59 bauzas I remember +2ing this
08:54:44 bauzas alex_xu: stephenfin: honesly, I feel it's hard to manage both at the same time, and I voiced it a couple of times in the spec review
08:55:13 alex_xu bauzas: here is the thing manage same time https://review.opendev.org/#/c/671801/46/nova/scheduler/manager.py@174
