21:31:36 cburgess mikal: Yes I still lurk here most days. You all are the only friends I have.
21:31:48 cburgess dansmith: Tax them? I mean argue with them I get, but tax them?
21:32:12 dansmith cburgess: yeah, I don't understand the logic either, but.. alas :D
21:32:19 cburgess LOL
21:32:49 dansmith but seriously, I'm thinking if you're the slow one, a long-range BBQ sauce spray bottle could be real handy
21:33:16 dansmith and, you didn't even technically perform an aggressive act, you just sauced up a buddy
21:33:27 dansmith so you get to keep your membership card and everything
21:37:40 mikal So that was the time dansmith defined covering a person with bbq sauce while being attacked by bears as an act of friendship.
21:37:44 efried You just know the early iterations of that spray were flammable
21:38:20 dansmith mikal: can you imagine a more loving way to feed someone to a bear than cover them in delicious BBQ sauce?

13:13:27 mriedem lyarwood: a few small things in https://review.openstack.org/#/c/551349/
13:26:33 mriedem gibi: heh found a use case for something we talked about recently https://review.openstack.org/#/c/387687/
13:27:01 mriedem compute node went down, admin unbinds a port to re-use it elsewhere, compute node comes back up and delete the old server and nova deletes the port
13:27:11 mriedem or unbinds it from the server it was currently bound to
13:31:52 gibi mriedem: hm, that sounds like a bug
13:32:23 gibi mriedem: nova should check if the port is bound to the same server as nova things to bound to before unbind
13:34:19 mriedem yeah there is an old bug for it
13:34:23 openstack Launchpad bug 1634269 in OpenStack Compute (nova) "Incorrect port unbind request on instance delete" [Low,In progress] - Assigned to AJAY KALAMBUR (akalambu)
13:34:23 mriedem https://bugs.launchpad.net/nova/+bug/1634269
13:34:44 openstackgerrit Matt Riedemann proposed openstack/nova master: Fix incorrect port unbind request in nova on instance delete https://review.openstack.org/387687
13:37:36 gibi OK, so in the fix we simply refresh nova's view based on neutron's view and only unbind if the vif is still belongs to the instance
13:37:42 gibi that could work
13:38:32 gibi in a similar scenario with bandwidth when neutron admin forcefully unbind the port then the resource allocation view will become inaccurate
13:39:39 gibi then when the old nova instance is deleted the whole resource allocation is deleted in placement so the inventory become correct eventually
13:41:06 gibi hm, in the bug, the instance is deleted while the compute was still down. I'm not sure when the allocation for such instance is deleted from placement
13:43:46 gibi OK. compute.api._local_delete calls delete_allocation_for_instance() so if the admin unbinds the port _after_ the instance is local deleted then the resource view is in a correct state
13:46:42 gibi mriedem: So I don't see that this sceanrio leads to any issue with bandwidth resource
13:46:48 mriedem this bug predates placement by a long shot
13:46:53 mriedem i'm not saying it does,
13:47:04 mriedem we have just talked about the weird corner case of unbinding ports out of band
13:51:18 gibi mriedem: yeah, the use case seems valid
13:53:50 openstackgerrit Jack Ding proposed openstack/nova master: Preserve UEFI NVRAM variable store https://review.openstack.org/621646
13:56:13 openstack Launchpad bug 1816399 in OpenStack Compute (nova) "The periodic task to clean up expired console_auth tokens is invalid" [Undecided,In progress] - Assigned to Takashi NATSUME (natsume-takashi)
13:56:13 mriedem melwitt: is this really stein rc potential? https://bugs.launchpad.net/nova/+bug/1816399 - isn't that a latent issue since rocky?
16:10:08 openstackgerrit Matt Riedemann proposed openstack/nova-specs master: Re-propose cross-cell-resize spec for Train https://review.openstack.org/642807
16:12:15 dansmith mriedem: regarding this: https://review.openstack.org/#/c/567701, where is the az set on the reqspec during live migration?
16:14:41 mriedem the request spec az is set on server create and never changes
16:15:10 dansmith okay I'm missing something about your assertion in the commit message then
16:16:07 dansmith you say the reqspec.az is what the az filter looks at, and that means the instance can be moved across azs, which I assumed meant we update it so after you move it it's correct,
16:16:20 dansmith but if not, then if you force a move across azs, and then do something like a resize,
16:16:34 dansmith the instance will pop back over to the old az during scheduling, yeah? Is that what you meant?
16:19:33 mriedem replied inline
16:20:38 dansmith mriedem: okay I'm more talking about the case where az *is* set
16:20:56 dansmith agree that if it's not set, it shouldn't matter, that's the easy case
16:21:18 mriedem i wasn't considering the force case here,
16:21:25 mriedem that's a separate f'ed up issue that evacuate will also suffer from
16:21:53 mriedem but yeah, if you request server create in AZ1, admin forces live migrate or evacuate to AZ2, and then the user resizes, they'll wind up back in AZ1
16:21:56 mriedem b/c of the request spec
16:22:07 mriedem another example of why we removed the force parameter
16:22:13 mriedem but it's a separate bug imo
16:24:25 dansmith mriedem: I'm more interested in the v2.1 case, since that's all that osc seems to support right now, which by my reading is kinda equivalent to force=True with a destination right?
16:24:43 dansmith mriedem: I'm actually asking about this for another reason, not for confirmation of your patch itself
16:26:54 mriedem "which by my reading is kinda equivalent to force=True with a destination right" yup
16:27:10 mriedem also,
16:27:16 mriedem https://docs.openstack.org/python-openstackclient/latest/cli/command-objects/server.html#server-migrate is totally borked in this regard,
16:27:24 dansmith yes
16:27:26 mriedem if you're using osc to do live migrations, you're *always* forcing by default
16:27:29 mriedem it's mega fucked
16:28:05 mriedem i've talked with dean about this and unfucking it means essentially a major version bump
16:28:10 mriedem b/c it has to be an interface change
16:28:46 mriedem what you're talking about with force not updating the request spec az is a latent bug yeah
16:29:41 mriedem https://review.openstack.org/#/c/627801/
16:30:20 mriedem maybe should queue that up for the ptg
16:33:48 mriedem mordred: i added an item to the nova train ptg etherpad about finally unbreaking the osc server migrate interface, since we should shit or get off that pot
