Bug with Prune task status

[pascalbrax]

Info: I run PBS with its own storage on the same virtual machine.



I have no complains, PBS does its job perfectly. I verify the backups automatically and manually sometimes with zero issues.

Every backup job is configured with a prune retention, here's how the task log usually looks like:



After each backup (OK) there's pruning (OK) and if I check the task, I get this:



But now...

After a while, I check the log and seems all the prune jobs are... unknown!



Backup tasks? OK! Prune jobs? Eh...

If i check those "Unknown" prune tasks, I get... nothing?



Everything else seems to work as intended, but I have no idea why did this start to happen and at this point I'm not sure what should I do?

Hi,
what PBS version are you running? Please post the output of proxmox-backup-manager version --verbose. Might be an issue similar to the one already reported for the daily update task (in german) https://forum.proxmox.com/threads/pbs-3-3-0-dly-update-status-unknown.158764/

Edit: I can reproduce this and will investigate. Thanks for the report.

Hi, here's my PBS version output:

I think you're into something, I've checked the German post you linked, and checked the journalctl myself and noticed something interesting:



The syntax output of proxmox-daily-update has been changed (the apt-get update output) between November 25 and 26, "TASK OK" is missing.

And the same happened with the tasks log on PBS:



Again, November 25: everything OK. From November 26: Unknown.

I found the issue and sent a patch with a tentative fix to the developers mailing list [0]. The issue with the unknown state for the daily update task should be fixed as well once the corresponding patch gets applied [1] (linked here for reference once again).
