[SOLVED] Error during PBS sync - create_locked_backup_group failed

[mocanub]

Hi everyone,

I'm trying to configure a sync between 2 PBS servers (PBS01 and PBS02 as per the below logs). For some groups it works without any issues but for some I get this error create_locked_backup_group failed. Both PBS servers are at version 3.1-2.

Does anyone know what is causing this?

2023-12-21T15:26:23+02:00: Starting datastore sync job 'pbs01:PBS01_VM_BACKUP:PBS02_VM_BACKUP::s-5a367ff1-0b29'

could you do "ls /mnt/datastore/PBS02_VM_BACKUP/vm/115/" and post the output?

Hi fabian,

Thanks for your reply.

So this is the group content on the source datastore PBS01:

$ ls /mnt/datastore/PBS01_VM_BACKUP/vm/115/ -la
total 52
drwxr-xr-x  6 backup backup  7 Dec 17 13:16 .
drwxr-xr-x 76 backup backup 76 Nov 14 22:53 ..
drwxr-xr-x  2 backup backup  6 Nov 26 12:11 2023-11-26T10:07:10Z
drwxr-xr-x  2 backup backup  6 Dec  3 12:04 2023-12-03T10:01:02Z
drwxr-xr-x  2 backup backup  6 Dec 10 12:12 2023-12-10T10:09:03Z
drwxr-xr-x  2 backup backup  6 Dec 17 13:17 2023-12-17T11:12:04Z
-rw-r--r--  1 backup backup 14 Jul  8 00:47 owner

and this is the group content on the destination datastore PBS02:

$ ls -la /mnt/datastore/PBS02_VM_BACKUP/vm/115
total 25
drwxr-xr-x  2 backup backup  2 Dec 19 14:19 .
drwxr-xr-x 66 backup backup 66 Dec 21 15:26 ..

 

[fabian]

delete the empty dir on PBS02, and then restart the sync..

Thanks a lot, @fabian.

That did the trick.
