#openstack-nova - 2021-02-24
15:38:14 sean-k-mooney the closes is proabnly line 59
15:38:31 sean-k-mooney but we shoudl ahve a wait before that if we were relying on it
15:39:23 lyarwood gibi: yeah so that's just to fail the call to detach a volume on the down compute, otherwise we'd wait for the default timeout to be hit.
15:39:52 lyarwood gibi: and yes it's normally a cast but thanks to castascall here we timeout
15:40:30 gibi lyarwood: hm so after the fix https://review.opendev.org/c/openstack/nova/+/768352 the change in the timeout is not used
15:41:08 gibi lyarwood: so what I see is that the _create_server fails in that test case sometimes for me locally as the scheduler calls the conductor to build the instance but the conductor takes more than 1 sec to reply
15:41:25 lyarwood ah yeah I see
15:41:31 gibi if I undertand correclty after the fix the shrinked timeout is not needed any more
15:41:36 lyarwood correct
15:41:52 gibi cool, then I will remove that to stabilize the func test on a small compute
15:42:03 gibi I mean on a slow node
15:42:13 lyarwood yup, apologies for missing that, I hadn't seen it fail anywhere like that while working on it
15:43:15 openstackgerrit Merged openstack/nova master: apidb: Add manage.py script https://review.opendev.org/c/openstack/nova/+/771419
15:44:11 gibi lyarwood: no worries. I tend to collect a list of unstable func and unit test I see locally and time to time go thought
15:45:24 stephenfin lyarwood: Think you could take a quick look at this stable patch? https://review.opendev.org/c/openstack/nova/+/751240
15:45:44 stephenfin Context is that it'll help a student working on openstacksdk patches for adding placement support
15:46:07 lyarwood stephenfin: yup looking
15:51:01 sean-k-mooney stephenfin: gibi lyarwood quick question https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/models.py#L1483
15:51:22 sean-k-mooney the dev_type filed in the db is restrited to a lenth of 8
15:51:27 sean-k-mooney type-vdpa is 9
15:51:42 gibi /o\
15:51:44 stephenfin drop type-
15:51:47 sean-k-mooney so shoudl i extend the column or just sotre vdpa
15:51:56 stephenfin it was silly in the first place
15:52:11 gibi OK, that works for me the type prefix seems redundant
15:52:15 sean-k-mooney ya i really doubt it save any space in reality
15:52:28 sean-k-mooney cool ill do that so
15:52:45 sean-k-mooney and ya the prefix is not really useful
16:15:55 prometheanfire sean-k-mooney: yep, thanks :D
16:16:07 prometheanfire stephenfin: meant that for you about the mock thing :D
17:52:35 openstackgerrit Clark Boylan proposed openstack/nova master: DO NOT MERGE testing a thing https://review.opendev.org/c/openstack/nova/+/777444
18:00:49 lyarwood gibi: https://blueprints.launchpad.net/nova/+spec/ephemeral-storage-encryption - I've moved this to Deferred, not sure if that's the correct state but I'm punting it to at least X, I'll document why upstream next week once I'm back from PTO.
18:01:36 openstackgerrit Clark Boylan proposed openstack/nova master: DO NOT MERGE testing a thing https://review.opendev.org/c/openstack/nova/+/777444
18:01:37 gibi lyarwood: thanks for that
18:01:52 gibi lyarwood: right now Deferred is OK, I will do the cleanup after FF anyhow
18:02:07 lyarwood gibi: ack cool
18:20:18 openstackgerrit Balazs Gibizer proposed openstack/nova master: Remove short call timeout from func test https://review.opendev.org/c/openstack/nova/+/777447
18:20:56 gibi lyarwood: a small fix for the func test we talked about ^^
19:06:47 gregwork can nova flavors be created that have multiple ephemeral disks?
19:06:59 gregwork i know you can nova boot --ephemeral x --ephemeral y
19:07:35 gregwork trying a nova flavor-create --ephemeral x --ephemeral y doesn't respect this via the CLI
19:13:12 sean-k-mooney gregwork: yes and no
19:13:24 sean-k-mooney you can have multiple ephmeral disk
19:13:36 sean-k-mooney i dont think you can spcify that in the flavor
19:13:52 sean-k-mooney i think you specify that durign instance creation
19:14:21 sean-k-mooney there is quite an obsucre way to do this ill see if i can find it but its not commonly used as far as i am aware
19:15:06 sean-k-mooney ok not that obscure
19:15:08 sean-k-mooney ova boot --flavor test-flavor --image cirros --nic net-name=test-network --ephemeral size=1,format=ext4 --ephemeral size=2,format=ext4 test-vm
19:15:34 gregwork so pick whatever flavor and just boot it with whats needed
19:15:35 sean-k-mooney gregwork: but basically the amount of space in the flavor can be subdevied during boot
19:15:54 gregwork oh
19:15:58 sean-k-mooney ya provided you dont excee the amount of space in the flavor its fine
19:16:14 gregwork do the value of "disk"
19:16:28 sean-k-mooney disk is root disk
19:16:45 gregwork yeah so im curious as to what you mean by the space in the flavor
19:17:06 sean-k-mooney therre are 2 storage vaules in the flavor
19:17:45 sean-k-mooney disk and OS-FLV-EXT-DATA:ephemeral
19:18:22 sean-k-mooney https://docs.openstack.org/api-ref/compute/?expanded=add-flavor-access-to-tenant-addtenantaccess-action-detail,create-flavor-detail#create-flavor
19:18:42 sean-k-mooney OS-FLV-EXT-DATA:ephemeral is what is used to limit --ephemeral
19:19:32 gregwork i was under the impression that that value is what will be attached as a separate volume to root
19:19:43 gregwork i did not know it could be sub divided
19:19:57 sean-k-mooney gregwork: some things to keep in mind are ephemeral disk are not snapshot so that also means they are not preserved on shelve
19:20:27 sean-k-mooney gregwork: most people dont if you dont pass any args that will be prented as a singel addtional disk to the instance by default
19:20:50 gregwork thats kind of cool
19:20:56 sean-k-mooney but if the flaovr has addtional ephemeral storage you can subdevide it
19:21:07 sean-k-mooney gregwork: the other thing to kep in mind is that resize is undefined
19:21:28 sean-k-mooney or rather resize where the epmeral size changes is undefiend (read broken as hell)
19:21:57 sean-k-mooney so its cool be there be dragons if you try to resize down
19:22:01 sean-k-mooney up might be ok
19:22:14 sean-k-mooney but again very rarely used feature
19:22:25 sean-k-mooney also very old i think it predate cinder
19:23:35 gregwork the situation we are trying to work around is this quick poc we are running needs fast disk and cinder is overloaded. So they are going to stuff some flash in 3 computes dedicated to this project
19:23:46 sean-k-mooney gregwork: if you want to do it with the openstack client you have to manually build the block device mappings dict and use the local volum type to do this
19:23:47 gregwork so we are going to run off the local ephemeral
19:25:20 sean-k-mooney as long as people are awrae fo the limiations, local scratch space is exactly what that flavor value is for
19:25:35 gregwork for sure, its a demo environment

08:50:44 nightmare_unreal Hi , can someone help me with the syntax to pass an empty list (to remove the RP) ? I am taking in reference to "resource provider aggregate set "
08:59:00 gibi nightmare_unreal: remove the RP from where?
08:59:45 nightmare_unreal gibi: placement aggregate
08:59:56 nightmare_unreal we discussed this few days ago
09:00:24 nightmare_unreal and you showed me this syntax : you can do openstack resource provider aggregate set <rp-uuid> --aggregate <agg1> --aggregate <agg2> ...
09:03:31 gibi OK, so you want to remove PRs from the aggregate
09:07:24 gibi nightmare_unreal: if you want to remove an aggregate then do not provide it in the set command
09:07:41 gibi nightmare_unreal: if you want to remove all the aggregates the provided zero --aggregate in the command
09:07:47 gibi example http://paste.openstack.org/show/802990/\
09:07:49 gibi example http://paste.openstack.org/show/802990/
09:08:31 nightmare_unreal yes i want to remove PR from the aggregate
