#openstack-nova - 2019-10-25
20:08:10 looking4somethin in nova.conf right?
20:08:13 melwitt there is also https://docs.openstack.org/nova/rocky/configuration/config.html#filter_scheduler.shuffle_best_same_weighed_hosts if you want to randomize hosts that are all weighed the same
20:08:34 melwitt yeah nova.conf
20:08:37 efried hm, CPUWeigher has a docstring that says spread is the default.
20:09:00 efried ditto RAMWeigher
20:09:18 melwitt here's the docs for all the weighers so you have to read those to see which one might be causing behavior you don't like by default https://docs.openstack.org/nova/latest/user/filter-scheduler.html#weights
20:09:36 efried phew, an rtfm answer, thanks melwitt
20:10:04 looking4somethin thanks melwitt
20:18:32 looking4somethin how can I replace (in nova.conf) nova.scheduler.weights.all_weighers by nova.scheduler.weights.CPUWeigher or just to select one weigher
20:19:12 looking4somethin I want to allocate to a node that have the most vcpus available
20:24:54 efried looking4somethin: It looks to me like you would say
20:24:55 efried [scheduler]
20:24:55 efried weight_classes = 'nova.scheduler.weights.cpu.CPUWeigher'
20:31:03 looking4somethin efried I will try it tomorrow, thanks
20:31:20 efried good luck
20:31:24 efried sweet dreams
20:31:28 efried (are made of this)
20:34:49 mriedem melwitt: efried: isn't that twice this week someone has been in here asking how to randomize allocations? wasn't eandersson asking about the same thing?
20:35:05 mriedem maybe we need a more obvious doc about the various knobs used to make that happen
20:35:12 mriedem since it seems like there are a few things to look at
20:35:17 efried except I think in both cases randomize turned out not to be the answer.
20:35:37 mriedem well, i don't mean the actual placement randomize option,
20:35:45 mriedem but shuffling a host within the same weighted subset
20:36:06 eandersson There are three options, and all seem very similar to me (especially if not reading the source code first)
20:36:37 mriedem my point is, can we get people to (1) stop reading source code and (2) find what they are looking for in the docs?
20:36:49 eandersson 100% this ^
20:36:54 mriedem i'm thinking about it b/c i've been working on a troubleshooting doc for orphaned allocations
20:37:11 mriedem which i'm about to birth
20:38:57 eandersson btw we did like 6k cold migrations and live migrations with Rocky
20:39:04 eandersson Don't ask me why :p
20:39:19 eandersson And 99% were successful
20:39:27 eandersson We had some really bad failures
20:39:35 eandersson The worst was some sort of neutron port corruption
20:39:51 eandersson where the port was on the wrong compute, and in some cases completely corrupt in the neutron db
20:40:49 eandersson But at least no orphaned placement allocations so that is great
20:44:39 openstackgerrit Matt Riedemann proposed openstack/nova master: doc: add troubleshooting guide for cleaning up orphaned allocations https://review.opendev.org/691427
20:45:15 mriedem eandersson: port issues with the host binding details specifically? because someone else had reported issues with live migrations and weird port binding UniqueConstraint issues
20:45:34 eandersson Yea I think so
20:45:49 eandersson I can probably dig up some more details
20:45:56 eandersson but nothing much in the logs unfortunately
20:46:58 eandersson live migrations actually worked pretty well overall in Rocky
20:47:26 eandersson But only when emptying one host and live migrating all of them into an empty host
20:47:31 openstackgerrit Matt Riedemann proposed openstack/nova stable/stein: libvirt: Ignore volume exceptions during post_live_migration https://review.opendev.org/691282
20:48:10 mriedem eandersson: https://review.opendev.org/#/c/653506/
20:48:26 mriedem ^ was the solution for the other person that reported that issue
20:49:05 mriedem so far obviously there hasn't been enough motivation to pick that back up and address comments
20:50:07 eandersson I am not too worried about it at the moment as live migrations only works in the above scenario for us
20:50:23 eandersson but maybe I can upgrade to Train in the lab and see if I can reproduce it.
20:50:32 eandersson And test that patch out.
21:08:00 mriedem i'm out

00:08:25 eandersson > ('Connection aborted.', BadStatusLine("''",))
00:08:44 eandersson I have seen a few bugs mentioning keepalive causing this issue (e.g. when computes are talking to neutron)
00:09:15 eandersson Anyone confirmed that disabling keepalive fixes it?

13:29:49 lyarwood LGTM
13:30:16 mriedem thanks
13:55:49 mriedem huh, apparently our api db in functional tests leaks across tests
