07:44:06 frickler melwitt: I didn't see the context for the ceph job discussion, but I'm certainly very much in favor of making it voting. after all that's what the large majority of deployments seem to be running.
09:58:44 ileixe Hi fork. o/ I'm curious how others deal with the notorious 'nosiy neighbor' problem.
09:59:48 ileixe I found there was related bp using intel LLC tunning though, it looks little bit tricky.
10:00:09 ileixe So.. I wonder the only viable solution for openstack is.. cpu pinning?

14:47:25 mriedem someone want to approve this for gate goodness? https://review.opendev.org/#/c/656633/
15:00:17 gibi_off mriedem: done
15:01:25 mriedem thanks
15:01:29 mriedem gibi_off: are you really off?
15:06:03 melwitt frickler: yeah it was just mriedem and I were talking about making the ceph job voting
15:07:38 gryf efried, could you please paste the link for this etherpad?
15:07:41 mriedem andreaf: hey, i copied something from the devstack-tempest playbook in tempest for a pre-run in nova and it seems to cause some wonkiness with devstack https://review.opendev.org/#/c/656656/2/playbooks/nova-multi-cell/pre.yaml
15:08:02 mriedem so i removed the "orchestrate-devstack" role since i'm not sure what it's for, of if it's needed for my pre-run pay
15:08:03 mriedem *play
15:08:13 mriedem andreaf: would you know if i actually need that?
15:08:26 mriedem i just need to run a play after devstack is done but before tempest runs so i can modify policy on the controller
15:08:52 mriedem everything else in my role works fine but that orchestrate-devstack thing seems to screw things up with starting glance-api

17:16:23 artom mdbooth, as in, in the same cloud you could have computes too old to support a thing (tags, multiattach)
17:16:34 artom Not the case anymore, but was a thing in the cycle when those were introduced
17:17:04 openstackgerrit Rodolfo Alonso Hernandez proposed openstack/os-vif master: Remove unused vif_plug_ovs.i18n module https://review.opendev.org/656815

17:37:45 stephenfin cdent: Wanna blindly approve some patches for me? https://review.opendev.org/#/q/project:x/wsme+topic:trivial+status:open
17:37:56 stephenfin cdent: Should probably kick off a 1.0 release then
17:44:30 cdent stephenfin: I removed myself from wsme, or at least meant to. Talk to dtantsur
17:45:00 dtantsur stephenfin: will approve when they pass the CI
17:45:17 stephenfin ta
17:45:45 dtantsur I'm not sure why I don't see them in my gerrty.. I wonder if something broke during the transition for me.
17:45:52 dtantsur ah, no, here they are

19:56:34 jroll did we ever finish the network aware scheduling thing? or is there some way to tie a network to an aggregate that I'm not seeing?
19:56:56 jroll I know that neutron's routed networks creates placement aggregates for each segment, do I just drop hosts into that aggregate?
19:57:12 mriedem mlavalle: ^
19:58:06 mlavalle jroll: in principle yes, but there is work pending in Nova
19:59:16 jroll mlavalle: ok, so right now if I connect the hosts to the aggregate, it won't stop nova from putting the 'wrong' network on the host?
19:59:30 mlavalle jroll: correct
19:59:37 jroll mlavalle: ok, thanks
19:59:48 jroll totally thought that was done already, sigh
20:00:11 mriedem jroll: no, osic laying everyone off working on it kind of ... stalled things out
20:00:34 jroll hasn't osic ruined my life enough already?
20:00:42 mriedem obviously not
20:00:56 jroll :|
20:00:59 mriedem if it makes you feel better, there are plenty of new intel specs to discuss at the ptg today
20:01:11 jroll that does make me feel better about not being there
20:02:10 mriedem i forget what we even need for linking the routed network aggregates
20:02:54 mriedem neutron creates a placement aggregate around the nova compute node resource providers in a given network segment, right?
20:02:59 jroll this is the most recent I could find: https://review.opendev.org/#/q/topic:bp/prep-for-network-aware-scheduling-pike
20:03:01 jroll correct
20:03:40 mriedem and when creating a server with a given network or port, we want to create the server on a host in the aggregate associated with that network
20:04:10 jroll correct
20:04:24 mriedem and placement aggregates don't have ids, so we can't just rely on some aggregate id being in the network meta for nova to use during scheduling
20:04:42 mriedem but the nova host aggregate has a uuid,
20:04:57 mriedem and if we could link the network to that aggregate uuid, then we could ....
20:04:58 mriedem idk
20:05:02 jroll seems like it would also fit in the get-me-a-network stuff - choose a network that can be used on the selected host
20:05:02 mriedem i'm confusing myself
20:05:12 jroll you're confusing me more I suspect
20:05:38 mriedem we have placement request pre-filters in the scheduler now that leverage placement aggregates,
20:05:47 mriedem i'm just trying to think through how we could do something like that for this
20:06:21 jroll I appreciate that :)
20:06:33 jroll I'm happy to talk post-ptg sometime to not distract you
20:07:51 mriedem oh ok,
20:08:12 mriedem so yeah, aggregates in placement are just a grouping concept of resource providers (compute nodes here), and the aggregate in placement is just an id,
20:08:53 mriedem if we had that aggregate id stored on the network resource in neutron, we could just translate that in nova during scheduling to say 'give me all allocation candidates (compute nodes) in that provider aggregate for this network'
