@SudoOracle Thx for chiming in!
Glad to know I'm not alone.
-
@olivierlambert I went back to my prior version, which was commit 04dd9. And the very next backup finished successfully. Not sure if this was a fluke, but I have backups going every 2 hours and this was the first to finish successfully today without me clicking the button to retry the backup. I'll report tomorrow on whether they continue to work or not.
-
Okay great, you can use
git bisectto easily find the culprit. Now we also need to find the common situation between you and @manilx : type of backup, advanced options enabled, type of BR, and so on to also understand more about this. -
@olivierlambert I have changed my backup strategy because of that:
Before:
Now:
After this the problem did no longer occur.
-
Can you sum up what you did? I admit I don't have enough time to investigate differences between 2 screenshots
-
@olivierlambert Sure!
I had a main backup job running 2 schedules, on bihourly and one last one at the end of the day, the latter one with healthcheck.
Then I had 2 Mirror incremental ones running after that, one to a local NAS and one to a remote NAS @office.
I now have separate backups for the bihourly, end of day and the 2 mirror ones (now they are delta backups directly to the NAS'es).
I hope this explains it.
-
Thanks. As soon the commit generating the error is identified, this will be very helpful for @florent
-
@olivierlambert I can then restore the config and retest once it's identified/fixed.... But just now I need the backups working without issues
-
So since I went back to an older version, I have not had a single backup fail. I have 3 main backups that run. 2 of them daily (my pool metadata/XO config and a delta of 18vms) and then 1 every 2 hours (also a delta but only of 3 vms). ALL of them would fail in one way or another, even the metadata. Something I just noticed now is it looks like each backup is starting twice or at least there are failed logs indicating so. If they are actually running twice that would explain the errors. This would also explain why clicking the retry backup option would always succeed.
Error from the metadata backup:
EEXIST: file already exists, open '/run/xo-server/mounts/c9199dfc-af05-4707-badb-8741e61daafb/xo-config-backups/f19069dd-f98b-4b41-9ca8-0e711fc75968/20250216T041500Z/data.json' -
@SudoOracle are you able to find the offending commit?
-
@olivierlambert Still working on it. It's between a4986 and 494ea.
-
@olivierlambert Just to confirm that the error have stopped since I changed the backup plans.
The change being to have only one schedule per job and not using Replicate jobs.
-
Ok so I'm not sure what happened but it's working fine now, I made it all the way back to commit 494ea and my backups continue to work. I have done nothing except move between commits. Maybe something happened when updating before? I am going to move to the latest commit and see if it continues to work.
-
@SudoOracle could you post the full json log of the backup ?
(you can get it by clicking on the download button on top of a failed execution job)if possible, one per type of failed backup job
-
@florent So it does seem to be working now. I'm on the latest version and backups are fine. Attached are the 2 jsons of the failed jobs. It's technically only the 1 backup, but there were 2 failed jobs per backup job.
