#openstack-nova - 2018-06-18
23:03:17 eandersson Is there a way to do live migration one-by-one in Mitaka? e.g. using some external script or similar?
23:04:05 eandersson with NUMA support
23:04:25 efried eandersson: I imagine you could do some kind of
23:04:25 efried for uuid in `nova list --params`; do nova migrate $uuid blah; done
23:04:25 efried But I suspect that's not what you're asking...
23:04:47 eandersson Ah yea, sorry left out an important detail about NUMA :p
23:05:44 eandersson Trying to figure out if there is a one-off script we could use to manually fix the NUMA calculation after live migrating VMs
23:06:48 efried eandersson: Ask stephenfin in about 12h
23:07:08 efried sean-k-mooney[m] may also be able to help, but he's also UTC.
23:07:20 efried cfriesen possibly?
23:08:27 eandersson Thanks efried
23:08:30 cfriesen eandersson: one issue is that you may not actually succeed in live migrating
23:09:12 cfriesen eandersson: since in the general case you need to recalculate any dedicated CPUs, guest-to-host NUMA mapping, etc
23:11:47 cfriesen If you could arrange things such that you have an empty compute node that is identical to the one you want to migrate off of, that would simplify things since they could all keep the same resources.
23:12:50 cfriesen eandersson: ^ (I suppose it would also work if dest compute node was larger than the source.)
23:20:02 eandersson cfriesen, yea we were thinking of disabling a compute node, and then live migrating to it
23:20:19 eandersson to avoid raceconditions etc
23:23:08 eandersson most of these vms are probably gonna take up a single numa zone, with two zones per host
23:30:09 openstackgerrit Eric Fried proposed openstack/os-vif master: doc: Fix arg specs and object types in docs https://review.openstack.org/575151
23:32:52 openstackgerrit Matt Riedemann proposed openstack/nova stable/pike: Fixed auto-convergence option name in doc https://review.openstack.org/576282
23:34:52 cfriesen eandersson: if it's disabled then nova won't let you live migrate to it
23:36:08 cfriesen eandersson: but as long as you can guarantee that the resources being used on the source host are available on the dest, then it should be basically okay. Once the resource audit has run on the dest (within a minute by default) then you should be basically sane.
23:46:29 mriedem for all you ceph nerds, this doesn't make a ton of sense https://bugs.launchpad.net/nova/+bug/1777123
23:46:30 openstack Launchpad bug 1777123 in OpenStack Compute (nova) "Nova 17.04 fails to create ephemeral storage with rbd driver " [Undecided,New]
#openstack-nova - 2018-06-19
00:13:56 mnaser mriedem: weird, we do CI within OSA which i believe includes spinning up a vm
00:14:05 mnaser with a ceph eploy
00:14:08 mnaser deploy*
00:14:29 mriedem we also have a ceph job
00:14:56 mriedem the bug doesn't really make sense, there shouldn't be anything unicode, as far as i can see, about the rbd_name we pass to the rbd code when building the driver
00:18:33 mnaser https://github.com/ceph/ceph/blob/master/src/pybind/rbd/rbd.pyx#L667-L687
00:19:06 mnaser if python <= 3 and its unicode, it converts it too
00:19:39 mriedem https://github.com/ceph/ceph/commit/72dc17ce327dc6422a2d62348b2c42971d364b6b
00:19:43 mriedem that was a pretty recent fix
00:20:30 mriedem i still don't see how nova is passing unicode for the rbd name
00:20:39 mnaser yeah we don't deploy that new in osa
00:20:53 mriedem but it's way down in image cache land so tracing where the values are coming from is really hard
00:21:39 mnaser unless
00:21:59 mnaser this user deployed latest ceph
00:22:04 mnaser and that bug is manifesting itself
00:25:07 mnaser i assume the ceph job tests luminous
00:25:57 mnaser 5 days ago ceph mimic became the new stable

08:50:33 Kevin_Zheng gibi, my pleasure, thank you for the review
08:51:35 vpc_ gibi
08:51:36 vpc_ can i ask
08:51:37 Kevin_Zheng gibi, I would like to help on anything if needed
08:51:53 gibi vpc_: sure, go ahead
08:52:25 vpc_ how can i take a snapshot of an instance with 3 volumes attached on hit
08:53:17 gibi Kevin_Zheng: in Stein I would like to put some extra effort finishing the versioned notification transformation as in Rocky I did not make much progress but only couple of notification is missing
08:53:37 gibi Kevin_Zheng: your work is appriciated there
08:53:44 Kevin_Zheng sure
08:53:48 Kevin_Zheng I would love to
08:53:54 gibi Kevin_Zheng: cool, thanks
08:53:55 vpc_ gibi any thoughts?
08:54:31 gibi vpc_: do you need live snapshot or offline?
08:54:50 vpc_ live snapshot of instance
08:55:16 vpc_ i snapshot my instance but it not get all volume attached on it
08:57:20 openstackgerrit zhangyangyang proposed openstack/nova master: Remove os_compute_api:os-config-drive https://review.openstack.org/576435
08:57:46 gibi vpc_: if you have 3 volumes then I guess you need to create 3 snapshots one for each
08:58:19 gibi vpc_: like calling this https://developer.openstack.org/api-ref/compute/#assisted-volume-snapshots-os-assisted-volume-snapshots 3 times
08:58:51 gibi vpc_: via cinder
