jopdorpand new volumes nicely end up as resources in gnocchi12:44
jopdorpbut i don't see the volumes which already existed12:44
jopdorpdoes anyone know a way to trigger cinder to create the volumes in gnocchi?12:44
jopdorpit needs to be triggered to send a message to ceilometer i guess12:44

CeeMacis it ok to ask questions or are you guys still in your meeting?14:32
CeeMacdont want to interrupt (except for I realise I am just now, but not more than necessary)14:32
*** brinzhang_ has quit IRC14:33
smcginnisCeeMac: You might not get responses right away, but ask away.14:34
CeeMacthanks14:34
CeeMacfollowing on from our chat yesterday, I've added a new backend and added it to a private type, and have successfully tested creating a new volume within the project in the access list (the type isn't available to the other projects)14:35
CeeMacso that's all great so far14:35
CeeMachowever, when I try and do a volume migrate I get a NoValidBackend14:35
CeeMacwhich references the exact same host as the was used successfully in creating the volume14:36
CeeMacso I'm a bit stuck on how to proceed and what is missing/wrong14:38
CeeMacor if actually migrate is the wrong process as its using a different type14:38
CeeMacbut the looking at the cinder retype command it didn't look like a valid option either14:38
CeeMacalso, its very hot and my brain has melted14:38
smcginnisCeeMac: Are you doing retype with --migrate-on-demand true, or actually calling migrate?14:38
CeeMaccalling migrate14:38
CeeMacopenstack volume migrate14:39
smcginnisI think in this case you actually want to do a retype.14:39
CeeMacah14:39
CeeMacright14:39
CeeMaci wondered14:39
openstackgerritSofia Enriquez proposed openstack/cinder master: PoC for Sizing encrypted volumes  https://review.opendev.org/74386914:39
smcginnisThey are an ongoing source of confusion. ;)14:39
CeeMacyeah, the documentation sounded a lot more clear when I originally read it to what the help files say14:40
CeeMacretype is cli only i guess14:40
CeeMaci can only see migrate volume in horizon14:40
smcginnise0ne: Do you know if Horizon exposes retype?14:40
smcginnisI would think it should.14:40
e0nesmcginnis: yes, it does14:41
CeeMacin rocky?14:41
e0neCeeMac: yes, it should be available in rocky14:42
CeeMacthat should be available under Admin | Volumes then the action menu of the volume?14:43
e0neit should be available for a regular users too14:44
*** udesale_ has joined #openstack-cinder14:44
*** geguileo has quit IRC14:44
e0neproject => compute => volumes panel14:44
CeeMaci thought migrate operations were admin only14:44
CeeMac"change volume type"14:44
smcginnisRetype is not.14:44
CeeMacretype calls a migration though? #confused14:45
*** geguileo has joined #openstack-cinder14:45
CeeMacI guess I'll try clicking on 'Change Volume Type' not idea how I didnt see that!14:45
hemnaI found the timeout issue in the ceph-iscsi ci job14:45
smcginnisNo, it doesn't call a migration, but if you say migrate-on-demand, it basically performs the same operation to be able to satisfy the new type.14:45
hemnagoing to try and reproduce it here14:46
CeeMacright14:46
*** udesale has quit IRC14:46
CeeMaci'll give it a go and come back14:46

CeeMacok, so migrate volume is only visible from admin, and 'change volume type' is only visible from project14:51

CeeMacok15:12
CeeMacso, using the 'change volume type' against the volume from the project | volumes area failed.  Scheduler found a host and allocated a volume creation task which succeeded on the chosen destination host. Then the source host failed with a forbidden error15:13
CeeMachttps://pasted.tech/pastes/a2bb62baa6d00baa511464e595b4bbfc77b2563415:13
CeeMacany thought?15:13
CeeMacsmcginnis: e0ne_15:13
e0ne_CeeMac: do you have any traceback in cinder-volume logs?15:14
e0ne_it looks like your can't attach some volume to perform the migration15:15
CeeMacyes15:15
CeeMacone sed15:15
CeeMacs/sed/sec15:15
CeeMachttps://pasted.tech/pastes/07e803dadec7dde1c2bd47f470454ae7d870f6d315:16
smcginnisThat's weird. I don't think I've ever seen a policy issue with attach calls.15:25
smcginnisCeeMac: Do you have a custom policy file that might be preventing updates?15:26
smcginnisLooks like maybe nova policy? Forbidden: Policy doesn't allow os_compute_api:os-volumes-attachments:update to be performed.15:26
e0ne_CeeMac: did you try to retype not-attached volume?15:26
CeeMacsmcginnis: not unless OSA creates a policy as part of deployment15:27
CeeMace0ne_: not yet, i'll do that just now15:27
CeeMace0ne_: retype of available volume was successful15:34
e0ne_ok, so probably it's multi-attach related issue15:34
smcginnisProbably makes sense. If it's not attached, then nova doesn't need to update the attachment.15:34
CeeMacso, i'll need to jump into the nova channel and prod someone there?15:35
smcginnisMaybe. You could probably check the contents of any policy files and see if there is anything obvious though.15:35
smcginnisSounds like it may be limited to admin or something.15:35
CeeMaci dont think this is going to prevent me from progressing with my requirement to add a new backend to provide storage for a new project, but i still need to work out a migration strategy15:36
smcginnisBut if this is the default policy, then that should likely change in nova.15:36
*** martinkennelly has quit IRC15:36
CeeMaci could try cinder retype from cli with admin creds15:36
*** martinkennelly has joined #openstack-cinder15:36
smcginnisCould be an interesting test to do this from the command line as an admin user to see if it is an admin/non-admin issue.15:36
smcginnis;)15:36
CeeMacsnap :D15:36
CeeMaclast time i saw a policy violation it was a user scoping issue, so hopefully admin will do it15:37

*** spatel has quit IRC15:45
CeeMacoh, final question (hopefully) is there a process for deleting a volume service / backend?15:45
e0ne_CeeMac: stop cinder-volume  service (or delete from the config in case of multi-backend configuration)15:46
e0ne_CeeMac: after this step you can check via 'cinder service-list' that the backend if in XXX state15:47
*** jv_ has quit IRC15:47
e0ne_to clean-up backends list there is a command in cinder-manage.py tool15:47
CeeMactried deleting the backend from the config previously and I still have 2 legacy volume services showing up as disabled15:47
CeeMacoh cinder-manage. right, need to dig out the docs for that15:48
e0ne_I didn't check if our docs cover it15:48
*** jv_ has joined #openstack-cinder15:48
