[SOLVED] "unexpected error on datastore traversal" error during garbage collection

[decibel83]

Hi,
I'm running Proxmox Backup Server 1.1-2, with storage on iSCSI.

Backups are running without problems, but I cannot prune any old backup because I get this error:

2021-04-28T07:33:53+02:00: starting garbage collection on store mydatastore
2021-04-28T07:33:53+02:00: Start GC phase1 (mark used chunks)
2021-04-28T07:33:53+02:00: TASK ERROR: unexpected error on datastore traversal: Bad message (os error 74)

Could you help me please?
Thank you!

Apparently the file system was corrupted, I solved running a fsck.
