09:29:52 sean-k-mooney nova manage
09:29:57 sean-k-mooney sure ill take a look
09:31:19 sean-k-mooney oh its a followup to https://review.opendev.org/c/openstack/nova/+/800855
09:31:51 sean-k-mooney ah yes i remember that
09:32:07 stephenfin thanks :)
09:39:01 sean-k-mooney +2 a minor unrelated formating chnage is included but im fine with that

15:20:05 opendevreview Merged openstack/nova master: tests: Add test for bug #1936278 https://review.opendev.org/c/openstack/nova/+/802893
16:22:44 opendevreview Sylvain Bauza proposed openstack/nova master: WIP: Fix verifying all the alloc requests from a multi-create https://review.opendev.org/c/openstack/nova/+/846786

03:56:49 opendevreview OpenStack Proposal Bot proposed openstack/python-novaclient master: Imported Translations from Zanata https://review.opendev.org/c/openstack/python-novaclient/+/846880
07:40:44 bauzas gibi: you maybe missed https://review.opendev.org/c/openstack/nova/+/846786
07:42:52 gibi bauzas: I think what you did is what we discussed. I would add some testing around the for:else: and the breaks but otherwise I agree with the direction
07:43:17 bauzas gibi: yup, of course, this is a WIP b/c I would add a UT
07:44:07 gibi so then that WIP looks OK to me
09:16:05 elodilles bauzas sean-k-mooney : can you please review the release patches (whether you see something that requires MINOR version bump, etc). I don't think it's worth to wait more time, as every week we'll have new patches + gate is sometimes slow and days are passing o:)
09:16:57 elodilles bauzas sean-k-mooney : of course if you see any patch that is a MUST to have in any of the release, then we can wait. but otherwise i think it's better to release now o:)
09:17:54 elodilles bauzas sean-k-mooney : and release managers won't review the release patches until PTL or release liaisons haven't reviewed the patches ;)
09:18:55 sean-k-mooney[m] actully i ment to update the patches
09:19:01 sean-k-mooney[m] to use the new sha last week
09:19:33 sean-k-mooney[m] most of the patches i wanted to wait for have alredy landed last week
09:19:50 sean-k-mooney[m] we just need to repin the patches to point to the currnent tip of the stable branches
09:21:02 sean-k-mooney[m] elodilles give me 10 mins to grab a coffee and ill go do that when i get back and +1 them
09:21:31 elodilles sean-k-mooney[m]: i've updated the patches with the latest hashes :)
09:21:50 elodilles sean-k-mooney[m]: no need to hurry as i also will go to have lunch ;)
09:22:38 elodilles so enjoy your coffee, and review the patches some time later today o:)
09:22:48 sean-k-mooney[m] oh ok thanks i stilll ment to do this last week so before i start anything else ill review them
09:23:28 bauzas elodilles: ack, will look
09:23:44 bauzas gibi: reopened https://bugs.launchpad.net/nova/+bug/1890244 fwiw
09:23:45 elodilles sean-k-mooney[m] bauzas: ++, thanks in advance! \o/
09:26:29 bauzas gibi: I'm curious how you didn't went able to reproduce the bug in https://bugs.launchpad.net/nova/+bug/1890244/comments/1
09:26:31 gibi bauzas: so probably CONF.workarounds.disable_group_policy_check_upcall was the trick why I was not able to reproduce it
09:26:42 bauzas gibi: hah
09:27:06 bauzas gibi: but IMHO we default to False
09:27:22 gibi then I dont know
09:28:11 gibi bauzas: did you reproduced it?
09:28:14 bauzas I need to respin my devstack env
09:28:42 bauzas gibi: no, I only triaged it and we have a downstream BZ that was related
09:28:49 bauzas https://bugzilla.redhat.com/show_bug.cgi?id=2099279
09:29:01 bauzas the code is pretty simple to look at
09:30:35 bauzas oh wait, you could be right, shit.
09:31:00 bauzas when we populate the ReqSpec, we rehydrate the fields and we can set the group value to None if the group was deleteed
09:32:04 bauzas https://github.com/openstack/nova/commit/94fd36f0582c5dbcf2b9886da7c7bf986d3ad5d1 is super old
09:35:35 gibi https://paste.opendev.org/show/bXPvHPVJ7FfPgjfhTsSv/
09:35:35 gibi I still cannot reproduce
09:37:46 bauzas gibi: then I don't understand
09:37:54 bauzas gibi: I verified master
09:38:07 gibi the above repro trial I run on master too
09:38:16 bauzas gibi: when we evacuate, we regenerate the old RequestSpec record
09:38:20 gibi I don't have a multinode train env
09:38:30 bauzas and then, we set the hints
09:39:57 bauzas gibi: can you look at your reqspec record and see whether you have the hints dict ?
09:40:06 gibi sure
09:41:07 gibi https://paste.opendev.org/show/baqepgHm3PhuQ9VhvfWi/
09:41:29 gibi there is the group hint in the dfb
09:41:30 gibi db
09:41:52 bauzas gibi: ok, and you can confirm that df92c028-728a-4321-9df6-6424ca56969e no longer exists in the instance_groups table ?
09:42:19 bauzas ideally we should introspect into https://github.com/openstack/nova/blob/ebe08834f311e8e22bfd9685d7e6e91dab967382/nova/compute/manager.py#L3657
09:42:44 gibi yes https://paste.opendev.org/show/b9NTbUJdRy4zI9qVlFsL/
09:43:22 bauzas gibi: could you see what we get as hints from https://github.com/openstack/nova/blob/ebe08834f311e8e22bfd9685d7e6e91dab967382/nova/compute/manager.py#L3656 ?
09:43:48 bauzas b/c I don't see where we could be smart
09:43:56 bauzas we're just getting the hints there
09:44:01 gibi I can add a LOG and repro give me 5
09:44:05 bauzas and see whether this is a group
09:44:26 bauzas if this a group, we directly lookup the instance_groups table with this UUID
09:44:37 bauzas and that's the upcall
09:45:57 sean-k-mooney so honestly im surpiesed we allow you to delete an instance group if there are instances in it
09:46:12 sean-k-mooney to me that is the really issue here
09:46:41 sean-k-mooney is there a reason we allow that
09:46:57 sean-k-mooney unlike the flavor for example we are not embdeding a copy fo the instance group
09:47:16 sean-k-mooney so we really should not allow ti to be remvoed if its in use
09:47:23 sean-k-mooney do we know why we do today?
09:48:44 bauzas sean-k-mooney: because Instance Groups are a terrible concept ?N
09:49:03 sean-k-mooney not nessiarly they may be implemented badly
09:49:23 sean-k-mooney the concept is not a bad one but the way we implemeted them is not good
09:52:56 gibi bauzas: could this be the reason we bail out https://github.com/openstack/nova/blob/ebe08834f311e8e22bfd9685d7e6e91dab967382/nova/compute/manager.py#L1742
09:53:11 gibi (still instrumenting the code with logs then I will rerun the repro attempt)
09:55:00 gibi btw I agree with sean that group is a better concept than same_host / different_host hints, as the hints were not reflexive
09:55:24 gibi strike reflexive
09:55:28 gibi symmetric
09:55:34 gibi they wasnt symmetirc
09:56:01 bauzas let's discuss this tomorrow at the bug call
09:56:04 bauzas shit, d/s
10:11:03 gibi I have /etc/nova/nova-cpu.conf:disable_group_policy_check_upcall = True in my env, restaring repro ....
10:12:25 sean-k-mooney isnt that our default
10:14:45 gibi nope
10:14:49 gibi the default is false
10:14:57 gibi I had an explicit True set for some reason
10:17:21 sean-k-mooney devstack set it to true by defualt i think
10:17:37 gibi yepp devastack by default does not even support the upcall
10:17:54 gibi so If I enable the upcall nova blows as no DB access
10:19:00 sean-k-mooney wait what
10:19:08 sean-k-mooney it shoudl be doing that via rpc to conductor
10:19:20 sean-k-mooney is it trying to use the old local conductor path
10:19:23 sean-k-mooney and directly access the db
10:20:37 gibi https://paste.opendev.org/show/bxWFPkh1OoBfWlM15mS0/
10:20:59 gibi it calls up to the cell conductor
10:21:06 gibi and cell conductor fails to read the api db
10:21:13 gibi as cell conductors has no access to the api db
10:21:14 sean-k-mooney oh
