Make use of the new "Storage Server", e.g. complete OSD backup

Description
Acceptance criteria¶
- AC1: The SUSE QA storage server is used within our production and we (the team) know what is used for
Suggestions¶
Ask nsinger where to connect to, what steps to start with?The hostname isstorage.qa.suse.deTry to connect to storage.qa with the same credentials as for osd machines maintained with salt, e.g. just ssh with your user should workSSH access should work at this point- Add changes and make sure the changes are in salt
- When populating the
btrfsfilesystemstorage.qa.suse.de:/storageit would make sense to create dedicated subvolumes for different things- e.g. do a full or partial backup of OSD
- e.g. mount storage.qa.suse.de:/storage on OSD and configure the archiving feature to use it
- When populating the
- What is included in a complete OSD backup?: To be answered by #96269
- Also include postgres? okurz: No, to be covered by #94015
- Which backups solution to use, e.g. rsnapshot?: okurz: Yes, use rsnapshot, same as we currently do on backup.qa.suse.de already
Further details¶
If we try to conduct a "complete OSD backup" by this we can also learn the performance impact, e.g. how long does it initially take to synchronize, how long does it take to do individual, e.g. daily syncs

Could we add some suggestions here and make it Workable? Like where to connect to, what steps to start with?

Yes, we should. I can't do much on that on my own though. nsinger knows more

Now with the archiving feature enabled one could try to mount storage.qa.suse.de:/storage on OSD and configure the archiving feature to use it.

- Related to action #92701: backup of etc/ from both o3 was not working since some days due to OOM on backup.qa.suse.de (was: … and osd not updated anymore since 2019) added

I've been updating the ticket description:
- There's an overlap between this ticket and #92701. I suppose if we opt for the full backup of OSD here we wouldn't need #92701 anymore. It also leads to the idea of only backing up
/etc(and maybe some other important directories) first. - It looks like
/storageonstorage.qa.suse.deis usingbtrfs. That makes sense and I suppose if we populate it with various things, e.g. an archive or backups we should create an own subvolume for these.

Now since we have the archiving feature enabling it is likely the easiest use of the storage server so I'll start with that.

We need to rethink. With https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/501 storage.qa.suse.de would become a critical component. So far what we have is a central VM that is backed by multiple levels of high-grade redundancy which we can see confirmed in years of flawless availability. And all the workers combined also provide built-in redundancy with our scheduling algorithm. The physical machine storage.qa.suse.de shows the single point of failure as visible in #93683 . I still see using storage.qa.suse.de as backup target as a good first approach. And I recommend to do that first. For the archiving feature we can still make use of that immediately as on osd we have expensive+fast and cheap+slow storage to be used
EDIT: Because we talked about if rsnapshot supports btrfs snapshots. The gentoo wiki mentions http://web.archive.org/web/20190910001551/http://it.werther-web.de/2011/10/23/migrate-rsnapshot-based-backup-to-btrfs-snapshots/ (the original page yields 404)

I haven't progressed here since we decided to focus on #92701 first. I'm unassigning because I won't be able to work on this until next Tuesday.

moving all tickets without size confirmation by the team back to "New". The team should move the tickets back after estimating and agreeing on a consistent size

Updated by okurz about 3 years ago
- Status changed from Blocked to Resolved
With #44078 completed we make active use of the storage space on storage.qa.suse.de and also that host is fully controlled with salt and actively monitored. Team agreed that we have AC1 covered :)
