21:36:45 mriedem mdbooth: ^ now i need to hook that into a multinode job
21:37:10 mdbooth mriedem: Reading, thanks
21:41:29 mriedem i'll throw it in the live migration job for now

22:31:49 mriedem gmann: question about https://review.openstack.org/#/c/602018/ - i don't see that renamed ceph job running on that branch
22:33:53 gmann mriedem: ohk, let me check

22:43:30 gmann i am trying to get tempest-full job fix in since 4.50 AM but random failure there.
22:48:35 mriedem gmann: yeah this is killing us http://status.openstack.org/elastic-recheck/#1783405

14:38:03 litao__ hi
14:39:15 litao__ This is my patch:https://review.openstack.org/#/c/592252/ I need some reviews , thanks

14:42:40 kashyap litao__: Hi, many folks are at a conference this week, so expect some delays in responses
14:45:43 mriedem dansmith: this was the thing i mentioned at breakfast re resize reschedule up-calls; do the proposed solutions inline make sense? https://blueprints.launchpad.net/nova/+spec/fix-reschedule-up-calls
14:50:22 mriedem bauzas: here is the fugly cross_az_attach=False bug fix i mentioned yesterday https://review.openstack.org/#/c/469675/
14:50:49 mriedem note that i plan on writing an alternate, less tightly coupled approach to fixing this laid out in https://review.openstack.org/#/c/469675/4/nova/compute/api.py@918
14:53:07 lyarwood bauzas: mind taking a look at https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bug/1787606 this morning if you get a chance
14:53:27 bauzas mriedem: ta, will look at both
14:54:37 mriedem edleafe: you might want to take a look at https://review.openstack.org/#/c/593074/ from lyarwood above
14:54:38 openstackgerrit Claudiu Belu proposed openstack/nova master: conductor: add live_resize task https://review.openstack.org/248579
14:54:39 openstackgerrit Claudiu Belu proposed openstack/nova master: API: Adds instance live-resize https://review.openstack.org/184584
14:54:42 bauzas lyarwood: yup, saw your change yesterday
14:57:34 lyarwood bauzas: well rebase, I'll fix the failing func tests if it's a valid fix
14:57:40 bauzas lyarwood: mriedem: could we just one day say we deprecate multiple instances creation ? :)
14:58:31 edleafe mriedem: One of the early discussions on alternate hosts was the concern about providing an alternate that may have already been consumed by another instance from the request. If that's no longer a concern, then that patch is fine.
14:59:00 bauzas edleafe: the problem is that we don't know yet if we will consume the host
14:59:09 mriedem edleafe: yeah that's what i mentioned to lya
14:59:20 mriedem *lyarwood
14:59:28 bauzas I mean, when it goes to pick a destination, we don't know yet if the allocation is possible
15:02:51 bauzas nevermind, we consumed the host before we get the alternates
15:03:19 mriedem i think the point is we don't want several reschedules trying to clobber the same alternate
15:03:25 mriedem maybe we should randomize the alternats?
15:03:28 mriedem *alternates?
15:03:28 edleafe bauzas: the selected_host has already claimed the resources at that point. Alternates only are provided if something else has prevented the selected host from bulding the instance. The feeling expressed when I wrote that is that we didn't want to include a host that already had some of its resources consumed
15:03:48 melwitt gibi: where did you send a mail about the minimum bandwidth scheduling demo location? I didn't see it
15:06:57 gibi melwitt: http://lists.openstack.org/pipermail/openstack-dev/2018-September/134622.html
15:07:58 bauzas mriedem: edleafe: yeah, the problem is that we don't optimize how we sort the alternates
15:08:20 melwitt gibi: oh, yeah, ok. the same one I read /facepalm
15:08:29 melwitt yesterday. I was thinking there was some other new one
15:08:40 bauzas mriedem: edleafe: meaning, instances could be optimized to be claimed spreadly, but then they could have the same host as alternate
15:09:01 gibi melwitt: if there was a new one yesterday then I didn't see that :)
15:09:08 bauzas so, yeah, we could just randomize the alternates, or find a better strategy
15:09:57 edleafe lyarwood: I'm curious as to the motivation for this. Have you seen a number of build failures on hosts that would require more alternates?
15:10:09 bauzas edleafe: see the bug report
15:10:20 bauzas in a small env, this could fail
15:10:23 bauzas 5 instances, 2 nodes
15:10:58 bauzas so, yeah, we're over rejecting
15:11:19 edleafe Ah, when you are requesting more instances in a single build than you have available hosts
