16:33:21 efried thanks mriedem
16:41:35 mriedem efried: how do you feel about having a mini personal goal of making https://github.com/openstack/nova/blob/master/nova/compute/resource_tracker.py#L985-L997 obsolete for in-tree drivers so we could deprecate or remove it in Train - out of tree drivers could be hit so if we wanted to be nice we'd just log a deprecation warning in T and remove in U
16:41:47 mriedem the only in-tree drivers that would hit those paths are xenapi and hyperv,
16:41:53 mriedem the former implements get_inventory,
16:41:59 mriedem the latter implements neither get_inventory or upt
16:43:27 mriedem oh looky here the hyperv out of tree driver has upt implemented https://opendev.org/openstack/compute-hyperv/src/branch/master/compute_hyperv/nova/driver.py#L464
16:44:49 efried mriedem: I'm big in favor of this. At some point I looked into doing it myself, but it (possibly hyperv) was going to be hairier than I was ready to deal with at that time.
16:46:17 efried mriedem: by "personal" you mean me or you? :P
16:46:45 efried stephenfin: I should wait to re-look at rootwrap series, yes?
16:47:14 mriedem efried: as in something we call each other about late on a friday night to talk about yes
16:47:16 efried stephenfin: The 'done' on the ipv4 patch is still forthcoming?
16:47:17 openstackgerrit Matt Riedemann proposed openstack/nova master: Fix update_provider_tree signature in reference docs https://review.opendev.org/667408
16:47:21 stephenfin efried: 2 secs
16:47:31 efried mriedem: ack, I like it.
16:48:08 stephenfin Actually, I want to test this more so I'll leave it til the morning
16:48:46 stephenfin efried: Sort of. I'm going to drop the first patch and then address the open TODOs in the remainder. If you want to take a look at any you haven't reviewed yet though, that could be helpful
16:49:38 efried something weird just happened
16:50:04 stephenfin Ohh, that's interesting
16:50:18 stephenfin I Ctrl + C'd git-review during the upload once I realized I'd more work to do
16:50:40 efried bot didn't notify, and when I look at the review it seems... corrupted.
16:51:23 efried the series isn't showing up on the right
16:51:32 stephenfin Feck it, I'll push it again just to fix that

16:53:06 efried that seems to have worked.
16:53:10 stephenfin Indeed
16:53:12 stephenfin and with that
16:53:20 efried why did you drop the bottom patch?
16:53:21 sean-k-mooney thats strang it should not have currpted it
16:53:52 stephenfin efried: It seemed like you didn't want it https://review.opendev.org/#/c/655282/
16:54:10 efried stephenfin: just one piece of it. The rest was good.
16:54:19 efried anyway, can do it elsewhere in the series
16:54:23 stephenfin Ah, then I can come back and stick that back in higher up in the series
16:54:31 efried ++ thanks stephenfin

18:55:40 mriedem efried: thoughts on only logging the warning on startup in ^ or every update_available_resource periodic?
18:55:58 mriedem the latter would be really chatty, but maybe that's the level of annoying we want
19:11:46 NewBruce evening all! mriedem have you seen this issue before mate?
19:11:46 NewBruce 2019-06-25 20:47:45.167 166805 INFO nova.compute.manager [req-bda9173a-31ed-447f-bf57-3ad85c565141 - - - - -] [instance: 5123fa51-512f-4f13-ae4b-5bbc7dd64e94] Migrating instance to cc-compute25-sto2 finished successfully.
19:11:46 NewBruce 2019-06-25 20:47:45.302 166805 WARNING nova.virt.libvirt.driver [req-bda9173a-31ed-447f-bf57-3ad85c565141 - - - - -] [instance: 5123fa51-512f-4f13-ae4b-5bbc7dd64e94] Error monitoring migration: Compute host cc-compute04-sto2 could not be found.: ComputeHostNotFound: Compute host cc-compute04-sto2 could not be found.
19:12:04 NewBruce got me stumped…. and why always me and migration issues? :)
19:12:31 NewBruce the instance is migrated, but is left in status ERROR
19:21:34 NewBruce Not sure if its related, but the source node is throwing this error… a lot
19:21:34 NewBruce File "/openstack/venvs/nova-18.0.0/lib/python2.7/site-packages/oslo_utils/timeutils.py", line 68, in parse_isotime
19:21:34 NewBruce raise ValueError(six.text_type(e))
19:21:34 NewBruce ValueError: year is out of range
19:36:51 Nick_A why is nova (?) metadata sending all /24 routes in a region to each instance? http://paste.openstack.org/show/y0lE42EA59yhnu7G1KnY/
19:39:01 mriedem bauzas: dansmith: i take it from the comments here https://github.com/openstack/nova/blob/master/nova/objects/compute_node.py#L150 that one shouldn't rely on ComputeNode.service_id is that correct?
19:39:13 mriedem the Service object has a compute_node field, and ComputeNode has a nullable service_id
19:39:23 mriedem but it looks like neither should really be used...
19:39:35 dansmith um, I dunno
19:40:35 mriedem ala https://github.com/openstack/nova/commit/551be2c52a29cb2755de4825a3fcb2c8f7d7b3f1 and https://github.com/openstack/nova/commit/0b177f18264ca842e16c2c989a081e773b3d86b7
19:40:44 mriedem ok, lots of really old compat notes from bauzas in all of that code
19:41:02 mriedem going back to kilo/liberty era
19:41:09 mriedem wonder if we'll ever clean that stuff up
19:41:11 dansmith yeah,
19:41:27 dansmith I'd think that that comment is probably old and that a migration fixed the ambiguity long ago, but.. I haven't looked
19:43:51 mriedem https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/models.py#L123
19:43:58 mriedem i don't think there was ever a migration
19:44:02 mriedem just lots of todos from ~liberty
19:45:57 dansmith hrm
19:45:59 mriedem ok i'd think the migration would be pretty simple,
19:46:08 mriedem iterate cells looking for compute_nodes where host is null
19:46:18 mriedem if so, find their service record and update the compute_nodes.host value
19:46:55 mriedem or a migration run per-cell (we haven't really be consistent there)
19:46:59 dansmith or just have computes update compute nodes on RT update
19:47:10 dansmith no reason to make it a manual-only thing
19:48:00 mriedem yeah i don't think it's even possible to get through RT with a cn that doesn't have a host value set
19:48:14 mriedem we lookup the cn by host and node and if it doesn't exist we create it and always have those values set now
19:48:34 mriedem so...maybe this is as good as a simple nova-status upgrade check to sniff out anything lingering and in U drop all of this compat code
19:48:43 dansmith sure
19:48:48 mriedem not sure we'd want to do the db alter table statements to make the column non-nullable...
19:48:54 mriedem but that's less of an issue
20:03:06 efried mriedem: upt also gets called on spawn & delete, doesn't it?
20:03:23 efried via update_available_resource
20:05:36 mriedem efried: i don't think so, you're thinking of instance_claim
