I noticed the disk usage was steady going up on one of our PBS servers.

So I started to look at the prune & GC logs.
Prune seems to be working. for example "2024-07-16T07:43:46+02:00: Pruning group proxmox:"vm/265""
But Garbage Collection does not seem to delete anything. Each day It just runs and says
I have temporary stopped the backups to prevent the disk from getting full.
Nothing has changed on the server so I'm really confused why this has started to happen.
root@ubp-pbs02:~# zpool status
pool: pbs-backup
state: ONLINE
scan: scrub repaired 0B in 1 days 08:10:24 with 0 errors on Mon Jul 15 08:34:26 2024
I have tried going to Datastore - storage - Content And manually clicking on the red trash bin on some older snapshots just so I can see that it really does clean out some older chunks. And then waited 24 hours and manually ran Garbage collection. But it still comes back with Removed chunks: 0 and Pending removals: 0
running Backup Server 3.1-4
Any useful tips or clues would be greatly appreciated
