| #openstack-nova - 2019-10-02 | |||
| 20:08:42 | dansmith | we talked about it in 2012 | |
| 20:08:47 | melwitt | efried, mriedem: added ^ to https://etherpad.openstack.org/p/nova-train-release-todo as a possible thing for RC2 | |
| 20:08:49 | sean-k-mooney | was it that long | |
| 20:08:49 | dansmith | but probably two years ago as well | |
| 20:09:14 | sean-k-mooney | anyway im glad its now a thing | |
| 20:09:24 | sean-k-mooney | because ya for edge it toptally makes sense | |
| 20:10:17 | sean-k-mooney | its resilent, spreads the load across multiple peers and works over low bandwitd links | |
| 20:10:24 | dansmith | I'm not really proposing that in the short term, but it's always been something I wanted us to do | |
| 20:11:18 | sean-k-mooney | well part of why i like it is its also not us e.g. openstack comping up with our own solution for a proablem that has and existing soltion already | |
| 20:11:33 | dansmith | yup | |
| 20:14:05 | mriedem | more comments | |
| 20:14:50 | artom | dansmith, brainstorming here - but does oslo.concurrency give us a distributed semaphore? | |
| 20:15:07 | dansmith | artom: not without some external service | |
| 20:15:11 | artom | I'm thinking - cast to the computes, but have the grab the semaphore when downloading | |
| 20:15:51 | bnemec | Sounds like a use case for tooz. | |
| 20:15:58 | mriedem | i was just going to make an etcd joke | |
| 20:16:08 | bnemec | oslo.concurrency only works within a single machine. | |
| 20:16:24 | artom | That way the concurrency becomes configurable (just set the semaphore's... err, cardinality?) and you don't ddos the glance server | |
| 20:16:26 | dansmith | artom: yeah, it's just not really necessary when we can threadpool it from the conductor | |
| 20:16:49 | artom | dansmith, for an RPC call though, right? | |
| 20:17:07 | dansmith | artom: yup | |
| 20:17:23 | artom | Yeah, I may be overthinking this | |
| 20:17:26 | mriedem | melwitt: ack i'm cool with that, docs only and regression in train | |
| 20:20:26 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/rocky: Noop CantStartEngineError in targets_cell if API DB not configured https://review.opendev.org/686276 | |
| 20:26:02 | dansmith | mriedem: yawna read my response to the parallelism thing and if you're cool with it I can squash those todos in my next rev: https://review.opendev.org/#/c/686232/4/specs/ussuri/approved/image-precache-support.rst@123 | |
| 20:26:02 | openstackgerrit | Merged openstack/nova master: Use os-brick locking for volume attach and detach https://review.opendev.org/614190 | |
| 20:26:12 | melwitt | mriedem: coolio | |
| 20:28:36 | mriedem | dansmith: replied | |
| 20:29:04 | dansmith | mriedem: thanks | |
| 20:30:52 | openstackgerrit | melanie witt proposed openstack/nova master: Restore console proxy deployment info to cells v2 layout doc https://review.opendev.org/686271 | |
| 20:35:06 | openstackgerrit | Dan Smith proposed openstack/nova-specs master: Add image-precache-support spec https://review.opendev.org/686232 | |
| 20:36:50 | efried | melwitt, mriedem: +2, good catch | |
| 20:38:58 | efried | aspiers: how's that SEV fixup looking? Would be nice to produce RC2 tomorrow (and not need RC3). Your fix is the last one I know of that's not well on the way to merging. | |
| 20:42:12 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/rocky: Handle get_host_availability_zone error during reschedule https://review.opendev.org/686292 | |
| 20:44:11 | mriedem | efried: deadline for RCs is oct 10 right? | |
| 20:44:19 | efried | yes | |
| 20:44:27 | mriedem | i mean, we want time for rc3 for sev issue #12 but sure | |
| 20:44:34 | efried | smy point | |
| 20:45:36 | efried | Oh, I misread, you're actually picking on SEV. I don't think we've had especially more issues for SEV than for other blueprints. Have there been more than one for any? | |
| 20:46:08 | efried | Seems like one for SEV, one for VPMEM, one for console tokens, one (?) for cpu-resources... | |
| 20:46:30 | efried | which is fine, exactly the reason FF happens before the release. | |
| 20:51:18 | sean-k-mooney | efried: i dont think we had any for cpu-resouce but we had/have one for numa migration | |
| 20:51:50 | sean-k-mooney | artom: has your fix for the RT cacheing issue landed? | |
| 20:51:58 | mriedem | yes | |
| 20:52:06 | sean-k-mooney | ok cool | |
| 20:52:12 | mriedem | console proxy was a docs thing | |
| 20:52:50 | mriedem | my point is sev landed late with a ton of churn over 2 releases (speaking as an outside observer to that series), so i wouldn't be surprised if there aren't more hairy issues | |
| 20:52:59 | mriedem | seems like every issue in that series is very hard to resolve | |
| 20:53:34 | mriedem | i also won't be surprised when there are issues with PCPU - we haven't seen issues because we're not using it anywhere yet | |
| 20:53:50 | mriedem | but in 18 months...watch out! | |
| 20:54:24 | sean-k-mooney | well there kind of is one but it was an issue we defeind as out of scope | |
| 20:54:31 | sean-k-mooney | it related to https://review.opendev.org/#/c/686079/ | |
| 20:55:52 | sean-k-mooney | you can only have flaoting instnace and pinned instance on the same host and not have mempage issue if you enable the numa aware memory tracking using hw:mem_page_size=<any valid value> | |
| 20:56:01 | sean-k-mooney | but we know it would not address that | |
| 20:58:55 | efried | mriedem: the console token thing we just merged? That wasn't a docs issue. | |
| 20:59:12 | efried | it may not have been related to an actual blueprint either though, not sure. | |
| 21:00:02 | sean-k-mooney | the console issue was passing the path argument in case it was not required right? | |
| 21:00:10 | dansmith | I think he means the cells console proxy doc thing | |
| 21:00:16 | efried | no | |
| 21:00:36 | efried | https://review.opendev.org/#/c/686066/ Reduce scope of 'path' query parameter to noVNC consoles | |
| 21:00:50 | dansmith | this: https://review.opendev.org/#/c/686271/ | |
| 21:01:14 | efried | no | |
| 21:01:16 | efried | -----^ | |
| 21:01:25 | dansmith | efried: I mean he==mriedem, not you | |
| 21:01:30 | efried | right | |
| 21:01:43 | efried | and confirmed it wasn't a blueprint, it was a bug | |
| 21:01:54 | efried | anywho | |
| 21:02:26 | sean-k-mooney | im going to call it a night o/ | |
| 21:05:49 | mriedem | efried: oh i wasn't thinking of the serial console thing | |
| 21:06:13 | mriedem | efried: it was a bug fix for a novnc 1.1.0 regression or something but dug a bit too deep | |
| 21:06:20 | efried | y | |
| 21:06:27 | mriedem | and actually wouldn't have been caught had it not been backported and released on stable | |
| 21:07:16 | mriedem | speaking of, dansmith can you get https://review.opendev.org/#/c/686063/ on stein so we can do a stein release tomorrow? | |
| 21:07:22 | mriedem | i think that's the last thing i was waiting on | |
| 21:07:38 | dansmith | okay | |

| 21:46:48 | ozzzo | Is there an "openstack" command corresponding to every "nova" and "nova-manage" command? | |
| 21:47:20 | ozzzo | For example, can I do "nova-manage service-disable <HV UUID>" via openstack? | |
| 21:48:49 | ozzzo | or "nova service-list" ? | |
| 21:49:11 | ozzzo | The obvious thing to try would be "openstack service list" but that does something different | |
| 21:56:23 | mriedem | yes, | |
| 21:56:31 | mriedem | https://docs.openstack.org/python-openstackclient/latest/cli/command-objects/compute-service.html#compute-service-set | |
| 21:56:47 | mriedem | nova-manage and nova/openstack CLIs are not the same | |
| 21:57:18 | mriedem | the former doesn't use apis, but hits the db directly when the api isn't available, and doesn't require a token, the latter requires a token and uses the api | |
| 21:57:40 | mriedem | you're also looking for this https://docs.openstack.org/python-openstackclient/latest/cli/command-objects/compute-service.html#compute-service-list | |
| 21:58:15 | ozzzo | very nice, thank you! | |

| 22:18:56 | ozzzo | Is there an "openstack" command for "nova-manage cell_v2 discover-hosts" ? | |
| 22:19:02 | mriedem | no | |
| 22:20:15 | mriedem | there is a config option to enable it in a periodic task if you don't want to hit the command line | |
| 22:20:30 | ozzzo | ok ty | |

| 22:27:36 | openstack | Launchpad bug 1845759 in OpenStack Compute (nova) "Openstack nova-compute service gives cant start new thread with oslo messaging" [Undecided,New] | |
| 22:27:36 | melwitt | mriedem: at first glance I wondered if this is related to the recent eventlet tpool proxy change, but it's reported against ocata https://bugs.launchpad.net/nova/+bug/1845759 | |
| 22:28:18 | mriedem | i saw it in triage but didn't have thoughts on it | |
| 22:29:32 | melwitt | me neither. I've never seen anything like it before | |
| 22:33:53 | ozzzo | I was thinking that "openstack compute service delete" would behave similar to "openstack resource provider delete" but the service did not come back when I typed "nova-manage cell_v2 discover_hosts" | |
