#openstack-nova - 2017-11-30
17:01:45 mriedem https://docs.openstack.org/nova/pike/configuration/sample-config.html
17:04:02 openstackgerrit Dan Smith proposed openstack/nova master: WIP: Genericify the instance_list stuff https://review.openstack.org/524253
17:04:03 dansmith mriedem: see if you don't not hate this ^
17:04:19 kashyap mriedem: Thanks. (So, it's this - ./doc/source/configuration/sample-config.rst)
17:04:24 dansmith mriedem: seems to work and be fairly straightforward actually
17:04:36 dansmith mriedem: I need to do a lot of cleanup and fixing the docs of course
17:04:50 dansmith but if you like that I will do that post haste and then we can ask the migration dudes to base on that
17:05:51 dansmith mriedem: look at the InstanceLister class for the things you have to implement in order to be cross-cell-listable
17:08:27 mriedem dansmith: i like it
17:08:41 mriedem yeah it delegates the db / object calls to the subclass impl
17:08:42 mriedem which is nice
17:08:44 dansmith right
17:08:49 mriedem only suggestion was using an abc at the top
17:08:51 dansmith might even be easier to digest if you're looking at it cold
17:08:57 dansmith I KNEW you were going to say that
17:09:08 dansmith almost put a comment like "Yes matt, I know"
17:09:34 mriedem that would be a fun easter egg
17:10:30 mriedem kashyap: looking at the libvirt driver i don't see that it returns 'stats' from get_available_resources
17:10:43 mriedem so i'm not really sure how that would work with the compute caps filter
17:10:58 kashyap Hmm
17:12:09 mriedem might be the cpu_info or supported_instances fields
17:12:20 mriedem those get put on the compute node record, which is the HostState object (wrapper) in the scheduler filter
17:12:35 mriedem no https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L7380 is for the cpu monitor metric stuff i think
17:12:38 mriedem which is a weigher
17:12:40 mriedem i think
17:12:52 mriedem i think you're looking for the cpu_info field on the compute node
17:13:03 mriedem https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L5826
17:14:51 kashyap Thanks for clarifying; I think that looks like it.
17:15:34 kashyap mriedem: dansmith: Speaking of Easter eggs, try this one -- https://unix.stackexchange.com/questions/405783/why-does-man-print-gimme-gimme-gimme-at-0030
17:15:37 kashyap :-)
17:15:55 kashyap It actually broke a _real_ use-case
17:16:26 kashyap But the 'man' authors were graceful enough to immediately admit that it wasn't supposed to affect error-scenarios, and fixed it right away.
17:16:40 kashyap (While still retaining the easter egg.)
17:17:23 kashyap (However, no one complained about that bug for _6_ years. So, it's edge case.)
17:18:16 openstackgerrit Merged openstack/nova master: check query param for server groups function https://review.openstack.org/500347
17:29:09 openstackgerrit Ildiko Vancsa proposed openstack/nova master: libvirt: Allow multiple volume attachments https://review.openstack.org/267587

17:31:40 cfriesen melwitt: (or anyone else) has bug 1469179 been fixed with placement/resource_providers?
17:31:41 openstack bug 1469179 in OpenStack Compute (nova) "instance.root_gb should be 0 for volume-backed instances" [Medium,In progress] https://launchpad.net/bugs/1469179 - Assigned to melanie witt (melwitt)
17:34:10 melwitt cfriesen: not yet. at the ptg when we discussed placement priorities, other items were more pressing, like alternate hosts and nested resource providers. so shared storage got bumped to rocky
17:39:00 mriedem melwitt: i've got a workaround for the compute node create / cell issue
17:39:03 mriedem pushing up shortly
17:39:07 mriedem it's uber hacky, but...
17:39:12 mriedem it's also pretty simple
17:40:24 melwitt okay, thanks. that'll help me determine what's wrong unless it's the periodic task thing from the fixture review
17:41:30 openstackgerrit Andreas Karis proposed openstack/nova master: Fixes 'Not enough available memory' log message https://review.openstack.org/524038
17:42:50 openstackgerrit Eric Fried proposed openstack/nova master: Proper error handling by _ensure_resource_provider https://review.openstack.org/524263
17:42:51 mriedem this isn't a periodic task issue
17:43:03 efried cdent jaypipes --^
17:43:10 openstackgerrit Matt Riedemann proposed openstack/nova master: Workaround CellDatabase fixture limitation when creating computes https://review.openstack.org/524264
17:43:10 openstackgerrit Matt Riedemann proposed openstack/nova master: Add multi-cell negative test for cold migration with target host https://review.openstack.org/524027
17:43:13 mriedem melwitt: dansmith: ^
17:43:28 cdent thanks efried
17:44:24 openstackgerrit Dan Smith proposed openstack/nova master: Genericify the instance_list stuff https://review.openstack.org/524253
17:44:25 cfriesen melwitt: okay, thanks. For the two patches that are up for review, are there problems with them or are they basically functional?
17:44:25 dansmith mriedem: melwitt: ^
17:46:34 melwitt cfriesen: some people prefer not to take the cruft that will have to be removed later, when resource providers work is going on and the bug/limitation has always been there
17:47:15 efried jaypipes Want me to address https://review.openstack.org/#/c/377215/ ?
17:47:19 melwitt other than that, the patches are basically functional (though in merge conflict right now) and don't pollute any database records with root_gb=0
17:47:22 openstackgerrit Matt Riedemann proposed openstack/nova master: Add multi-cell negative test for cold migration with target host https://review.openstack.org/524027
17:47:23 cfriesen melwitt: I'm just wondering about taking it as a local patch...we previously had fixed it a different way in Newton
17:48:11 cfriesen melwitt: I expect we'll pull them in and try them out.
17:49:01 mriedem dansmith: ack, will hit that after lunch
17:49:04 melwitt mriedem: it pains me how similar that is to what I'm trying to do with my patch. I just don't get what I missed yet
17:50:06 mriedem ease that pain with pills
17:50:16 dansmith mriedem: I'm thinking I need to follow up with a split of that file into the generic listing infrastructure, and the instance part of that so that the migration dudes can do the same
17:50:57 mriedem yeah, so instance_list is the instance-specific impl, and we'd have migration_list with that specific impl
17:51:02 mriedem and some generic module in between
17:51:18 mriedem not sure what that would be called? multi_cell_list?
17:51:25 dansmith yep something liket hat
17:51:30 dansmith sound good?
17:51:33 mriedem yeah
17:52:16 openstackgerrit Merged openstack/nova master: Remove setting of version/release from releasenotes https://review.openstack.org/520373
17:52:27 jaypipes efried: I can do that. are there any of your changes you haven't pushed?
17:53:10 jaypipes efried: in particular, I'll rebase through 520246, so make sure I don't overwrite any of your work...
17:53:28 efried jaypipes No, but note that I want to break away the stuff above
17:53:41 efried jaypipes Sorry, redo: No, don't rebase that far up.
17:53:52 efried I'm breaking off the subseries starting at uuid_set()
17:53:55 jaypipes efried: where should I go to.
17:53:57 jaypipes ok.
17:54:02 jaypipes no prob. gimme a few minutes
17:54:15 efried So just rebase from https://review.openstack.org/#/c/385693/ (which needs a rebase onto its predecessor too)
17:54:57 efried jaypipes ^
17:55:09 jaypipes ya
18:01:33 cdent efried: left some questions on that bug fix, looks mostly good, but I’m curious about some bits
18:01:48 efried cdent Ack, thanks for the review. Looking...
18:04:10 openstackgerrit Dan Smith proposed openstack/nova master: Split instance_list into instance and multi_cell https://review.openstack.org/524302
18:07:44 mgagne mriedem: so I reread the placement documentation and it's kind of clear already what you need to do. There are some details which need to be updated such as mention of cellsv1. I will pass through the doc again and see if it's clearer for me now.
18:10:51 openstackgerrit Jay Pipes proposed openstack/nova master: placement: allow filter providers in tree https://review.openstack.org/377215
18:10:52 openstackgerrit Jay Pipes proposed openstack/nova master: placement: update client to set parent provider https://review.openstack.org/385693
18:10:52 openstackgerrit Jay Pipes proposed openstack/nova master: placement: adds REST API for nested providers https://review.openstack.org/384807
18:10:55 jaypipes efried: done
18:11:05 efried jaypipes Cool mon.
18:13:01 openstackgerrit melanie witt proposed openstack/nova master: Improve the CellDatabases test fixture and usage https://review.openstack.org/508432
18:13:02 openstackgerrit melanie witt proposed openstack/nova master: WIP Store a RequestContext on service to reuse for periodic tasks https://review.openstack.org/524306
18:14:42 melwitt mriedem: the test in https://review.openstack.org/#/c/524027 passes with the above ^
18:16:38 openstackgerrit Eric Fried proposed openstack/nova master: Proper error handling by _ensure_resource_provider https://review.openstack.org/524263
18:16:50 efried cdent Not sure if I addressed your concerns here ^
18:17:23 efried cdent I wouldn't think it necessary to say, "Exceptions raised from here may be caught, logged, or ignored by callers as appropriate"
18:19:11 efried cdent Really just brings things more in line with other methods in SRC, like _update_inventory_attempt which may raise InventoryInUse
