02:11:55 melwitt like if you wait for the first instance to become active and then do another request, would it fail
02:11:58 johnsom Yeah, probably. This used to work.
02:12:41 johnsom Yeah, I don’t know about waiting for active. That can take some time.
02:13:46 johnsom We have seen that up to five minutes, mostly scheduler time. I don’t think we want to hold up the boot process for the secondary that long
02:14:30 melwitt no sorry, I meant in your devstack
02:15:15 melwitt I can try it later too but not tonight. I was just asking in case you had that easy environment already up
02:15:21 johnsom Ah, as a test. I can try that. It will be tomorrow however, it is dinner time. Lol
02:15:27 melwitt same
02:15:52 johnsom If there is a list of thing you would like me to try, comment on the bug and I will run them tomorrow
02:15:57 melwitt there's a thing called the "late affinity check" in nova-compute that is on by default that should handle races
02:16:35 melwitt I don't know off the top of my head what could have regressed this.
02:18:03 melwitt I'll try out some things with a devstack tomorrow to start finding out what's going on
02:18:46 melwitt efried: potential regression alert ^ fyi https://bugs.launchpad.net/nova/+bug/1863190
02:18:46 openstack Launchpad bug 1863190 in OpenStack Compute (nova) "Server group anti-affinity no longer works" [Undecided,New]
02:18:53 johnsom Ok, thanks. I will hold this instance through tomorrow in case we need it
02:21:14 melwitt k thanks

12:41:43 sean-k-mooney bauzas: i think you missed some of efried's comments. like explainging the fallback query.
12:42:29 sean-k-mooney efried: also did you see my suggestion to have teh numa=false host be added to an aggreate so we can use forbiden aggreates for that case https://review.opendev.org/#/c/552924/21/specs/ussuri/approved/numa-topology-with-rps.rst@235
12:46:33 sean-k-mooney over all however i think there is enough we agree on that we can proceed with this and adject with a fix up patch later based on implementaion discussions
12:47:43 sean-k-mooney i am off today so im not going to be around but i might see pings in the evening as my irc client will be connected

13:48:05 bauzas sean-k-mooney: again, I explained this
13:48:55 bauzas sean-k-mooney: oops my bad, I didn't passed my draft comments
13:48:59 bauzas sean-k-mooney: see them
13:49:31 bauzas stephenfin: can you please review it ? https://review.opendev.org/#/c/552924/

15:03:58 melwitt johnthetubaguy, bauzas: thank you both for your review on the nova-audit spec ++

15:10:57 melwitt alex_xu: hey, did you mean to hold off on +W on the unified limits spec? https://review.opendev.org/602201
15:25:17 openstackgerrit Alexandre arents proposed openstack/nova master: Avoid allocation leak when deleting instance stuck in BUILD https://review.opendev.org/702368
15:31:27 alex_xu melwitt: I'm ok with spec, just see bauzas whether want to look at that again
15:31:42 bauzas alex_xu: the unified limits one ?
15:31:44 melwitt alex_xu: cool, thanks
15:31:45 bauzas I can take a look
15:32:09 alex_xu np
15:42:31 efried alex_xu, johnthetubaguy: and also stephenfin: bauzas: gibi: Would you please have a look at https://review.opendev.org/#/c/580336 (delete on termination) and see if it's ready to +A today?
15:43:50 bauzas efried: /me opens a tab
15:44:18 efried sean-k-mooney, bauzas: I'm looking at the NUMA RP spec again right now. Based on comments I skimmed on my phone, I think we might have missed the boat on the `False` thing. But checking...
15:44:53 bauzas efried: when we discussed this with stephenfin, we agreed on splitting between non-NUMA and NUMA-aware nodes
15:45:13 bauzas so, if you say 'no' for a node, then you shouldn't get NUMA-aware instances
15:45:52 bauzas it's like 'no, I don't want to get a beer', but then the bar tender gives you one
15:46:08 efried bauzas: exactly, and there was a design hole for that in PS21.
15:46:49 gibi efried: ack
15:48:12 openstackgerrit Brin Zhang proposed openstack/nova-specs master: Support re-configure deleted_on_termination in server https://review.opendev.org/580336
15:50:13 bauzas efried: ok, look then at the new revision and tell me then if you see some hole
15:50:19 efried bauzas: now I think I understand that you got rid of the fallback query completely, and on purpose. But that doesn't work. The upgrade issue that gibi and stephenfin identified still exists.
15:50:42 efried bauzas: Specifically: without the 'fallback query', NUMA-aware flavors can't land on `None` hosts.
15:51:06 efried But *with* the fallback query, NUMA-aware flavors will *also* (incorrectly) land on `False` hosts.
15:51:08 bauzas efried: ah, possibly
15:51:14 bauzas shit
15:51:55 efried So we need a) the fallback query, and b) some other design element to fix that second problem.
15:52:08 efried sean-k-mooney's suggestion of using an aggregate... that will work, but it seems like a big hammer to me.
15:52:16 bauzas or using another trait then
15:52:22 efried I think I would prefer marking `False` hosts with a `NO_NUMA_HERE` trait... yes
15:52:28 bauzas like HW_NON_NUMA
15:52:40 bauzas ok, I think we can do this
15:52:58 efried It's not pretty. But it's also *temporary*. Once all computes are upgraded to V where the conf is mandatory, we can get rid of that, because we also get rid of the fallback query.
15:53:16 efried please be sure to mention ^ that.
15:53:22 efried sean-k-mooney: does that work for you?
15:53:32 bauzas a trait for which nodes then ?
15:53:47 efried for U+ nodes where the conf opt is marked False explicitly.
15:53:47 bauzas for those having 'false' right?
15:53:49 efried y
15:54:06 bauzas ok, because then we will use the trait even after V
15:54:09 efried no
15:54:37 efried I mean, it wouldn't *hurt* to keep it, but it won't be needed after V.
15:54:41 bauzas if so, I'd prefer to have a trait on 'none'
15:54:45 efried can't
15:54:54 bauzas actually you're right
15:55:00 efried because we can't muck with T hosts
15:55:03 bauzas and yeah we can still have the trait
15:55:07 bauzas in V
15:55:23 bauzas and for example, stoppint to have it when we want (V or W)
15:55:26 efried We could. But we wouldn't need it anymore. But we can make that decision in V. Just mention that we *could* get rid of it if we wanted to.
