GC error

[aychprox]

Hi,

I try to run GC and encountered following error:

root@pbs:~# proxmox-backup-client garbage-collect
Error: unable to get (default) repository

In PBS GUI, when click on the GC, it shows:

unable to get exclusive lock - EACCES: Permission denied

May I know what causes this error and how to rectify?
Thanks in advance

root@pbs:~# proxmox-backup-client garbage-collect
Error: unable to get (default) repository

here you have to choose a repository e.g.

proxmox-backup-client garbage-collect --repository mydatastore

(see docs for more detail)

In PBS GUI, when click on the GC, it shows:

unable to get exclusive lock - EACCES: Permission denied

whats the output of

ls -lha /path/to/your/datastore/

?

mhmm.. according to https://wiki.samba.org/index.php/LinuxCIFSKernel cifs only started to support flocks with kernel 5.5 (pbs has kernel 5.4).... so it seems having the datastore on cifs is not fully possible at the moment...
can you maybe open a bug on https://bugzilla.proxmox.com to track that issue?

I had open a bug on this issue.

By the way, may I know how to manually remove the unwanted backup aka the backup "garbage"?
Tried to use prune to remove, but overall disk use size still remain .....

Had the same issue.
I fixed it by installing pve-edge 5.8 kernel found at:
https://github.com/fabianishere/pve-edge-kernel

From kernel 5.5 there is flock support in samba.
