17:22:51	kplant	jkulik: for the record, the problem seems to have been that the AZ which the instance was created for no longer existed
17:22:59	kplant	the resize function kept reqesting an AZ with the original name
17:23:21	kplant	so i just created an AZ with that name. not sure if that's intended behavior
17:30:41	johnthetubaguy	kplant: if you requested the AZ in the first place, I believe that is expected
17:32:39	kplant	johnthetubaguy: you're everywhere :-)
17:33:10	johnthetubaguy	heh, sometimes
17:41:16	openstackgerrit	John Garbutt proposed openstack/nova master: WIP: Fix up quota classes APIs https://review.opendev.org/712749

17:51:19	stephenfin	johnthetubaguy: if you're about for another few minutes, care to finish off the remove-nova-network series? https://review.opendev.org/#/c/703974/
18:06:06	openstackgerrit	melanie witt proposed openstack/nova master: Add config option for neutron client retries https://review.opendev.org/712226
18:15:36	sean-k-mooney	anyone know where the placement inventory class is defiend in nova
18:21:00	sean-k-mooney	ok its not a class or object its just a random dict https://github.com/openstack/nova/blob/2f88e09609ee3075d675c1c41358f23901e56bce/nova/compute/provider_tree.py#L63
18:22:10	sean-k-mooney	ah # dict of inventory records, keyed by resource class
18:22:16	sean-k-mooney	that is what i was looking for
18:33:22	openstackgerrit	Sasha Andonov proposed openstack/nova master: rbd_utils: increase _destroy_volume timeout https://review.opendev.org/705764
18:43:50	openstackgerrit	sean mooney proposed openstack/nova master: Provider Config File: YAML file loading and schema validation https://review.opendev.org/673341

18:46:16	openstackgerrit	Stephen Finucane proposed openstack/nova master: Handle flavor disk mismatches when resizing https://review.opendev.org/712766
18:49:43	stephenfin	melwitt: did you # scsi > 7 patch land? Have you a link?
18:50:58	melwitt	stephenfin: what? the scsi limited to 7 thing is a libvirt bug. previous to that bug, the limit was 26 and a patch of mine from stein changed it to be configurable
18:51:16	melwitt	which thing are you looking for?
18:51:38	stephenfin	Ah, I got that assways, sorry /o\
18:52:00	stephenfin	I was conflating the two
18:52:06	stephenfin	https://bugs.launchpad.net/nova/+bug/1864279
18:52:06	openstack	Launchpad bug 1864279 in OpenStack Compute (nova) "Unable to attach more than 6 scsi volumes" [Undecided,New]
18:52:16	stephenfin	trying to find a dupe to associate with that
18:54:26	melwitt	stephenfin: ok, just looked. yeah, I remember we discussed downstream whether to propose a patch that basically checks "!= 7" and skips, but the consensus was for libvirt to fix its bug
18:56:12	melwitt	and apparently that did not happen yet? this has been going on for a long time and it looks like we need to talk about it again
18:57:21	melwitt	it doesn't really seem right for us to have to cover over the libvirt bug. and I don't know why it's not getting fixed on their side
18:57:50	melwitt	last I heard, they said they were fixing it
18:58:01	stephenfin	I've no idea whether it has been fixed yet or not. Could be that the fix just hasn't been backported? I can poke danpb or kashyap about it in the AM
18:58:31	stephenfin	I'm tempted to close this bug as not an issue here though. It's clearly a libvirt issue
18:58:35	melwitt	yeah I mean it seems not fixed if these ppl are hitting it
18:59:03	stephenfin	The only resolution I feel we could do is add a warning for the affected versions. We have done that before, in fairness
18:59:04	melwitt	but yeah def let's ask danpb or kashyap tomorrow
18:59:44	stephenfin	cool, I'll do that and consider adding the nova runtime version check if it's worth it
19:00:16	openstackgerrit	Merged openstack/nova master: Run sdk functional tests on nova changes https://review.opendev.org/712092
19:00:23	openstackgerrit	Merged openstack/nova master: [Trivial] Fix code comment of admin password tests https://review.opendev.org/711734
19:06:12	melwitt	stephenfin: here's the bug ticket https://bugzilla.redhat.com/show_bug.cgi?id=1744079 says it's fixed, so need to look at what versions this is showing up in? maybe they just need to update or maybe a backport is missing like you said?
19:06:12	openstack	melwitt: Error: Error getting bugzilla.redhat.com bug #1744079: NotPermitted
19:07:02	melwitt	sorry that was a clone https://bugzilla.redhat.com/show_bug.cgi?id=1741782
19:07:02	openstack	melwitt: Error: Error getting bugzilla.redhat.com bug #1741782: NotPermitted
19:09:57	kplant	if i have a instance on say "compute-01" and virsh shows it there, but nova thinks it's on "compute-02" how can i fix that?
19:12:29	stephenfin	melwitt: Yup, looks like this is the commit we need https://github.com/libvirt/libvirt/commit/c8007fdc5d2ce43fec2753cda60fb4963f55abd5
19:12:50	stephenfin	$ git tag --contains c8007fdc5d2ce43fec2753cda60fb4963f55abd5 | head -1
19:12:52	stephenfin	v5.10.0
19:15:20	melwitt	stephenfin: hm that looks like it. but v5.10.0 doesn't match the fixed in versions on the rhbzs? I don't understand that
19:17:29	stephenfin	backport, I'd say
19:17:41	melwitt	cause according to that there should be a fix in the 4.5.x series too
19:17:47	melwitt	yeah..
19:18:15	stephenfin	okay, I definitely don't think we need to do anything here in nova so
19:18:51	stephenfin	The bug's there. People can find it via their favourite search engine and annoy their vendors to backport the fix if needed
19:20:10	sean-k-mooney	we cant rely on backport in downstream version upstream
19:20:21	melwitt	yeah, agreed nothing to do in nova. I was trying to find some links to leave in the lp bug but I realize I don't know how upstream libvirt works, how to tell them what version etc
19:20:38	sean-k-mooney	so until we can raise the min libvirt version to 5.10 we cant assume that commit is there
19:21:18	melwitt	well, shouldn't upstream libvirt be backporting like we do for stable? or do they not do that
19:21:33	sean-k-mooney	melwitt: upstream libvirt does not do backports
19:21:48	stephenfin	I left some words. Hopefully they help
19:22:15	sean-k-mooney	melwitt: which is why each os vendor needs to do it downstream which is annoying
19:22:23	melwitt	dang
19:35:47	melwitt	dansmith: I added you to this review bc it's updating code that has a NOTE with yo name on it https://review.opendev.org/705764
21:58:21	openstackgerrit	melanie witt proposed openstack/nova master: DNM: try to get some debug info for bug 1844929 https://review.opendev.org/701478
