tobias-urdincinder seems to leave a lot of cinder-<uuid>-delete_(volume|snapshot) files in /var/lib/cinder08:47
tobias-urdincan't find any cinder-manage command to cleanup this, any process for this? or information what's causing these to get left over, they are just empty files.08:48
tobias-urdinit's not the image_conversion_path nor the lock_path which are /var/lib/cinder/conversion and /var/lib/cinder/tmp respectively08:49

smcginnistobias-urdin: I believe those are lock files.12:26
smcginnistobias-urdin: There was a long debate awhile back whether there was a good way to handle those, but not really.12:26
smcginnistobias-urdin: The only safe way to delete them all is to shut down all cinder services and then rm them.12:26
smcginnistobias-urdin: Might be better configuring tooz to use etcd, but not really sure.12:27
tobias-urdinsmcginnis: can cinder utilize any tooz-supported backend? memcache, redis etc12:28
tobias-urdinwonder why they are directly in /var/lib/cinder when lock_path = /var/lib/cinder/tmp12:30

smcginnistobias-urdin: We use tooz as the interface, so I would assume any tooz supported backend should work.13:22
smcginniscrazik: I believe that is backwards. It used to allow just the module path, but now requires the full path to the driver class.13:23
smcginniscrazik: But yes, I don't like needing to go to the DB for things, but that should work and be (mostly) safe.13:23

tomtom001hello, I'm trying to run a Cinder Backup of a detached volume.  The process starts but never finishes.  The only thing reported in the logs is DB connection error to the Galera cluster.  Has anyone ran into this issue or situation before, where the process starts but does not finish?  Does anyone know if the DB connection error reported in the logs is a concern or related to the unfinished16:17
tomtom001backup?16:17
*** vivsoni_ has joined #openstack-cinder16:17
smcginnistomtom001: I haven't seen that, but that error would definitely be a concern.16:19
smcginnistomtom001: I'm also not sure if Galera is fully supported. We don't test with that upstream at least.16:19
smcginnistomtom001: If you can upload your cinder-backup log somewhere, I can try to take a look for any other clues.16:20
vivsoni_Hi Team, please review https://review.openstack.org/#/c/587438/16:20
tomtom001Yeah I deployed using openstack ansible, it creates a galera cluster to run the openstack services db.16:20
tomtom001vivsoni_ I'll take a look at that.16:20
smcginnisOh, OK. Hadn't heard they were using that before.16:20
vivsoni_tomtom001: Thanks16:21
*** gkadam has quit IRC16:21
*** Bhujay has quit IRC16:22
tomtom001vivsoni_ that's for volume deletion?16:23
vivsoni_tomtom001: yes16:23
tomtom001smcginnis: here is the log file: http://paste.openstack.org/show/728983/16:24
tomtom001vivsoni_ does the process of Cinder Backup try to delete the volume at some point?  Or is it just looking for the task and can't find it?16:25
smcginnisWell, that's a small snippet of the log. I was thinking if you could post more before or after the traceback we might be able to see something else that could be leading to the failure.16:27
tomtom001sorry, i will post more16:27
smcginnistomtom001: This does look like it would be an issue though - "Lost connection to MySQL server during query"16:28

smcginnisHmm, yeah. Not a lot to go on there.16:38
smcginnistomtom001: What release are you running?16:39
tomtom001Newton - about to upgrade to queens16:41
smcginnisAh, there's been a lot of fixes since Newton. Might be better to upgrade and see if you still hit this issue.16:42
tomtom001Yeah, that's actually what I was thinking too.16:42
tomtom001I thought if there were a quick fix though I could push it in there.16:42
smcginnistomtom001: Yeah, always nice to know you are in good shape *before* upgrading. But I haven't seen this error, so I don't have any suggestions for clearing it up other than picking up all the changes with an upgrade, unfortunately.16:43

vivsoni_thanks tommylikehu, Sean & Jay for review16:56
smcginnisvivsoni_: What was the pep8 error?16:56
jungleboyjvivsoni_:  That doesn't seem right.  It should be down lower in the imports.16:56
vivsoni_smcginnis: i will share the exact error message16:57
jungleboyjShould be down with the other from oslo_* imports.16:57
smcginnisvivsoni_: Oh, you're using importutils to try to import the hpe client. There's a better way to do that.16:57
vivsoni_jungleboyj: ok jay. i agree with you to be lower16:57
vivsoni_in import16:58
vivsoni_but pep8 was giving some error16:58
vivsoni_let me share that with  you16:58
smcginnisvivsoni_: Instead of using importutils, just do it like this - https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/drbdmanagedrv.py#L4516:58
smcginnisvivsoni_: And that really should also have a check in check_for_setup_error that if client is None to log the reason the driver can't be used and fail out.17:00
