Backup jobs run twice after upgrade to 5.76.2
-
@tts said in Backup jobs run twice after upgrade to 5.76.2:
upgrade to v5.76.2
I think you meant 5.56.2.
Do you recall what version you were previously running?Maybe this is unrelated but when starting xo-server, we noticed syslog entries about two non existent plugins
Yes... this is unrelated and benign.
FWIW, I updated my system yesterday and I haven't seen this issue. There was a prior thread that you may want to review.
-
You are right @Danp, there was a typo. The correct version is 5.56.2 and was upgraded from 5.41.x
As for now I restored the XO vm snapshot to the previous version to test the upgrade again using the mentioned upgrade method in the docs.
I will report back if this issue is reproducible.

Hi,
we were not able to reproduce this, the backup jobs are again started only once. So good so far.
When stopping the xo-server.service I noticed some unhandled error events repeated 3 times, is this something we should care about?

@tts Can you tell us more about this current error?
- What method did you use to stop the XO service?
- What tasks / jobs were active at the time?
- Is this error reproducible?
- Etc
-
I used the systemd service template from /opt/xen-orchestra/packages/xo-server/xo-server.service,
which needed modifying the ExecStart path for xo-server from /usr/local/bin/ to /opt/.../xo-serverThe service was stopped using systemctl, but as I see now, there is no ExecStop directive in the service file, so I guess it just caught a SIGTERM from systemd?
We did not use the 'forever' approach from the docs as I thought the systemd file is there for a reason.
There were no active jobs visible when stopping the service, however Backup-NG showed a CR job still running since 2am for one vm but neither the taskview in XO listed something, nor did 'xe task-list'
-
@tts Sounds like the backup job was still in the middle of the "merge" process when you stopped the service. You should investigate if your destination VM is intact or needs a full backup.
-
Normally, the job should have been finished hours ago, all of the CR jobs start at 2am and are mostly finished within an hour.
But this time, only half of the vms were backed up 7 hours later, restarting the 'hanging' CR job for this particular vm finished successfull within minutes.
But you could be right, the job status switched from running to interrupted after restarting xo-server.

I will check the jobs tomorrow morning to see if this happened again and maybe could be related to the latest upgrade. On previous version 5.41 we did not encounter any 'hanging' backupjobs.
-
Unfortunately, our CR jobs are not working properly after the upgrade. Some get backup successfully, some just facing randomly hanging jobs, not just pinned down to one particular VM as we thought first.
It looks like it suddenly stops transferring the deltas / importing the vdi. We noticed some strange backtrace errors in xensource.log, which are related to the point of time of backing up the VM.

The only way to get out of this state is restarting xo-server.
Then the job switches to interrupted. If we start the backup again (restart failed or restart whole backup-job) the problematic VM eventually will back up successfully but the job will get stuck again, while backing up another randomly VM, leading to the same errors in the logs.
Please help, I am absolutely out of any ideas how to solve this. The remaining backups (delta, snapshot) are working as expected, only CR is now problematic.
-
Try with XOA to see if you can reproduce the issue there.
-
Additional to the above errors, we noticed a lot 'VDI_IO_ERROR' errors during the running jobs.
I remember there was a similar problem with CR which got fixed using the 'guessVhdSizeOnImport: true' option. Did anything change since then?
I will try with XOA trial when I have some spare time.
EDIT:
Can we import the config from our XO from sources to XOA or should we setup everything from scratch? -
Some addional info that might be relevant to this issue:
When stopping / starting xo-server after a hanging job, the summary sent as report is interesting as it states that the SR and VM isn't available / not found - which is obviously wrong..

Today I got XOA trial ready and imported config from XO-from-sources. Manually started CR jobs are working. Will test it with scheduled CR next couple of days.

Right now one of my CR jobs are stuck, symptoms are the same as with XO from sources.

Ping @julien-f

There is probably a problem in XO regarding this because we have received multiple similar reports, we are investigating.
-
@karlisi I've been unable to reproduce the issue so far, can you tell me which version of XO has the issue and which one does not?
Also, if you could provide me with your job configuration it would be nice
