| noonedeadpunk | Hi everyone. After Q -> R upgrade, cinder-volume started failing with this error http://paste.openstack.org/show/732829/ Previously this problem was non-critical, and didn't influence on cinder | 14:30 |
| noonedeadpunk | We have some manually created volumes inside this ceph pool, and we were going to migrate these images to cinder (via cinder manage) within some time | 14:31 |
| noonedeadpunk | I've found some common bug https://bugs.launchpad.net/cinder/+bug/1698786 which has been fixed by e0ne some time ago | 14:32 |

| jgriffith | but I realize it might be for some | 14:40 |

| mriedem | hello cinder people. looking at the backup API reference, it says only available (not in-use/reserved/etc) volumes can be backed up https://developer.openstack.org/api-ref/block-storage/v3/#backups-backups | 16:02 |
| mriedem | but i'm not really finding in the code where that status check happens... | 16:02 |
| mriedem | oh nvm i found it | 16:03 |
| mriedem | https://developer.openstack.org/api-ref/block-storage/v3/#backups-backups | 16:03 |
| mriedem | oops | 16:03 |
| mriedem | elif volume['status'] not in ["available", "in-use"]: | 16:03 |
| mriedem | oh look there, you can backup attached volumes... | 16:03 |
| smcginnis | mriedem: There's a force option in the request args - https://developer.openstack.org/api-ref/block-storage/v3/?expanded=create-a-backup-detail#create-a-backup | 16:03 |
| mriedem | yeah the api ref is misleading when it says "Backup and restore operations can only be carried out on volumes that are in an unattached and available state." | 16:04 |
| mriedem | should have a caveat about the force flag | 16:04 |
| mriedem | i'll push a change | 16:04 |
| *** udesale has quit IRC | 16:06 | |
| mriedem | still trying to hash this out https://review.openstack.org/#/c/530214/ | 16:11 |
| mriedem | if you backup a volume-backed server, do you get a volume snapshot or a volume backup | 16:11 |
| mriedem | i would think the latter | 16:12 |
| smcginnis | Yes, that later. | 16:12 |
| smcginnis | It will take a snapshot to be able to backup from, but it will be a backup. | 16:12 |
| mriedem | i mean, as a user i would expect a volume backup | 16:12 |
| smcginnis | And that snapshot will be deleted after the backup is complete. | 16:12 |
| mriedem | the createImage api in nova creates a volume snapshot of each volume attached to the server, and then records metadata about those snapshots in the image | 16:13 |
| smcginnis | It doesn't do anything else with the snaps? | 16:13 |
| mriedem | you get an image snapshot and N volume snapshots where N is the number of volumes attached to the server, including the root volume, | 16:15 |
| mriedem | metadata about those volume snapshots is recorded in the image meta, | 16:15 |
| mriedem | and if you create a new server from that image, nova-compute will actually create a volume-backed server from the volume snapshot and attach new volumes for any of the data volume snapshots | 16:16 |
| mriedem | otherwise referred to as image-defined BDMs | 16:16 |
| mriedem | and that's apparently a pretty common thing in EC2 | 16:16 |
| mriedem | but it's not used often in openstack i don't think - it's pretty confusing | 16:16 |
| smcginnis | It concerns me there's nothing protecting those externally referenced snapshots, but short of making them full backups (and requiring all that to be configured) or uploading them as glance images, I guess that's OK. | 16:16 |
| mriedem | anywho, we don't really even want the createBackup API in nova anymore, | 16:18 |
| mriedem | it could all be done externally, it's just orchestration | 16:18 |
| mriedem | create a snapshot with some metadata for rotations and then manage rotations yourself | 16:18 |
| mriedem | same could be done with volume-backed servers | 16:18 |
| smcginnis | Does nova do scheduling and retention for backups? | 16:19 |
| mriedem | scheduling? | 16:20 |
| mriedem | oh, like a cron | 16:20 |
| smcginnis | Yeah, that meaning of scheduling. | 16:20 |
| smcginnis | Cinder does not. We just provide the mechanism to get a backup with the expectation that you will use Karbor or your own scripting to actually orchestrate anything beyond that. | 16:21 |
| mriedem | nova is the same | 16:21 |
| mriedem | you create backups with a type (daily/weekly) and max number | 16:21 |
| mriedem | so the next time you create a backup, we check to see if any older backups should be deleted | 16:21 |
| mriedem | but that could all be done externally | 16:21 |
| smcginnis | Where does that daily/weekly come into play? | 16:22 |
| smcginnis | Oh wait, I see. | 16:22 |
| smcginnis | So nova does do a little more orchestration beyond just creating a backup. | 16:22 |
| smcginnis | We don't do that. | 16:22 |
| openstackgerrit | Dmitriy Rabotjagov (noonedeadpunk) proposed openstack/cinder master: Fixes bug, when cinder-volume fails on broken RBD image https://review.openstack.org/612741 | 16:23 |
| smcginnis | It's entirely up to something external to manage the lifetime of the backups and anything else that needs to happen to them. | 16:23 |
| mriedem | right, and that's kind of what we want people to be doing as well | 16:23 |
| mriedem | since we already have the createImage API which handles volume-backed servers | 16:23 |
| smcginnis | Makes sense. | 16:24 |

| jungleboyj | e0ne: I think it was from the User feedback where there were a number of requests to be able to schedule backups. The answer we kept coming back to is that that isn't really Cinder's job but for one of the external services or user automation. | 17:40 |
