17:15:21 mriedem heads in the sand and whatnot
17:16:13 melwitt I think we switched our default network backend to ovn recently. sean-k-mooney correct me
17:16:18 mriedem artom: if you're cool with dropping the nova-live-migratoin rename + resize revert stuff (i still thing the rename is good at some point, just not while hurrying for a fix) i'm ok with adding a depends-on from my unskip to your fix
17:16:25 sean-k-mooney hehe well for 15 we were planning to test with ovn but it has other issues
17:16:39 mriedem ooo the plot thickens
17:16:48 artom mriedem, 🤝
17:17:01 artom (That's a handshake shaped like a yellow heart)
17:17:10 mriedem ok - yeah pidgin doesn't render those
17:17:29 melwitt I can see it. looks cool
17:17:35 artom sean-k-mooney, so what's geneve? another name for OVN?
17:17:40 sean-k-mooney melwitt: yes but ovn has only works when we disabel waiting for the network-evnets on live migation so i think they wanted to test ml2/ovn with iptabls as a fallback plan
17:17:45 artom 'cuz that's the default networking thingee in our ospd custom job
17:17:59 sean-k-mooney geneve is a l3 tunneling protocol like vxlan
17:18:20 sean-k-mooney and its the protocol ovn uses for its networking by defualt
17:19:02 sean-k-mooney artom: you are refering to the neutron type driver which for ovn would be geneve
17:19:16 artom sean-k-mooney, "Choose the network variant (default for OSP15 is 'geneve')
17:19:16 artom For the geneve option set the NETWORK_OVN paremeter to yes."
17:19:26 artom (Form the Jenkins job build page)
17:19:32 artom So yeah, looks like OSP15 default is OVN
17:20:13 sean-k-mooney mriedem: but to your point yes this has always been broken in one way or another
17:21:09 openstackgerrit Artom Lifshitz proposed openstack/nova master: Revert resize: wait for events according to hybrid plug https://review.opendev.org/644881
17:21:09 sean-k-mooney but we i think we only started waithing in stien so its only showing up now as they are testing Stien/osp15
17:22:08 artom sean-k-mooney, I guess you can abandon https://review.opendev.org/#/c/660782/ now, since we're settling on https://review.opendev.org/#/c/663405/1
17:23:20 sean-k-mooney am sure i never intended it to merge anyway so if you dont need it for testing then sure ill abandon
17:24:05 artom We could replace it with another DNM on top of mriedem's tempest patch to run tempest-slow with hybrid plug
17:24:12 artom For the extra confidence
17:24:34 artom But we've seen it pass already, not sure how necessary a new patch would be
17:24:51 sean-k-mooney well i can add a depens on to matts change too but ok ill just abandon it
17:25:13 artom Well no you can't, because your change was in the multinode job
17:25:30 artom Whereas mriedem's change unksips a test in tempest-slow
17:25:53 sean-k-mooney yes but may change didnt diable tempest-slow
17:26:00 sean-k-mooney but anyway its abandoned
17:26:20 sean-k-mooney you know how to reporduce this if you need to so i dont need to keep a patch open
17:26:43 artom I need lunch

18:02:32 mriedem bugtastic
18:05:57 sean-k-mooney mriedem_lunch: the comment help but ya that looks correct
18:32:47 efried I wonder, if we made a bug whose title referenced another bug, and that bug's title referenced the first, could we make patchbot spin forever?

20:58:00 efried nova meeting in 3 minutes in #openstack-meeting
20:59:11 melwitt mriedem: ack
21:02:16 efried nova meeting now
21:07:23 mriedem no meeting?!
21:07:28 mriedem was reviewing something...
21:28:25 melwitt mriedem_afk: +1 to proposed wording
21:43:02 openstackgerrit Dustin Cowles proposed openstack/nova master: WIP: Use SDK instead of ironicclient for add/remove instance info from node https://review.opendev.org/659691
21:53:14 tonyb kashyap: I don't but it's on my list of things to get workign this year
21:53:19 tonyb kashyap: 'sup?
22:14:36 openstackgerrit Merged openstack/nova master: [Docs] Update the confusing console output https://review.opendev.org/589004
22:47:09 mnaser alright. has anyone ever ran into this? i'm convinced this feels like an oslo bug or something.
22:47:31 mnaser i've noticed that if i have a 3 node rabbitmq cluster, and the cluster loses a node and regains it, for some reason, its like nothing gets routed across rabbitmq
22:47:43 mnaser in this case, an instance gets booted and goes into SCHEDULING state and gets stuck forever
22:48:41 mnaser this is with rabbitmq 3.6.16 -- the only way i've solved it often is by deleting all the queues and restarting nova
22:48:54 mnaser the one 'odd' thing is with osa, we deploy a cluster with ssl for rabbitmq
22:49:32 mnaser i have a (non-prod) cluster stuck at this state right now and i really want to get to the bottom of what/why
22:51:01 mnaser all queues listing 0 messages.. except for notifications
22:59:40 melwitt mnaser: feel like you're going to need to get some other operator input about that one.. I haven't personally heard of it
23:00:03 melwitt imacdonn ^
23:00:06 mnaser melwitt: i've ran into it a bunch of times and had others who ran to it and the "drop all queues" thing fixed it..
23:00:26 melwitt I also asked penick to look at your messages here and let us know if he's seen it
23:01:18 mnaser melwitt: yay cool thanks, i'm going to continue digging, this is a non prod environment so i have the time to dig into it
23:01:25 mnaser usually things are under fire when i need to do this
23:01:38 melwitt yeah, that's awesome you got a repro in non-prod
23:02:14 mnaser feels like it's gonna be a really annoying one though
23:03:26 melwitt yeah. another person we could ask is kgiusti, he knows oslo.messaging
23:04:22 mnaser so, instance in scheduling state, 7 messages in a bunch of scheduler_fanout_* queues
23:04:44 mnaser but nothing happening, so i guess the conductor is doing what its suppoed to do
23:04:58 penick @mnaser we've had weird issues with rabbitmq and ssl. Mostly with performance and the queue faceplanting though. I don't think we've ever had to wipe and recreate all queues.
23:05:24 mnaser :( sads, yeah, it's pretty destructive but not sure..
23:05:28 penick Though the way we worked around the ssl issue is we switched from native SSL to using stunnel. Which is awful
23:05:38 penick something about native rabbit ssl is borked
23:05:42 mnaser oh wow, is the native rabbit ssl that bad
23:05:48 mnaser can i ask what release were you running then (or now)?
23:05:54 penick Ocata
23:05:58 penick oh, of rabbit
23:05:59 penick uh, one sec
23:06:05 mnaser thanks :>
23:06:12 mnaser there is exactly 48 scheduler_fanout_* queues
23:06:54 mnaser each controller has 16 nova-scheduler processes, which adds up to 48
23:07:08 mnaser so the theory is nova-conductor is doing its job but the scheduler just isn't picking up work off the queue..
23:07:56 penick 3.6.15
23:08:09 melwitt penick: I wondered whether it might be related to queue mirroring or non, clustered or non, how it behaves when a node leaves and rejoins
23:08:22 mnaser yeah we're at 3.6.16 so we're not far away
23:08:38 mnaser melwitt: yeah so actually i wondered if that was maybe the issue..
23:08:46 imacdonn FWIW, I don't run clustered rabbitmq - just a single instance
23:09:01 melwitt I had thought there might have been some configuration where that doesn't work well, but I can't remember anything more about it
23:09:12 mnaser imacdonn: you're living life
23:09:40 melwitt :D
