I've got:

root at lisei:~# zpool status -xv
  pool: rpool-hdd
 state: ONLINE
status: One or more devices has experienced an error resulting in data
	corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
	entire pool from backup.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A
  scan: scrub repaired 0B in 00:37:50 with 1 errors on Sun Nov 12 01:01:53 2023
config:

	NAME                                            STATE     READ WRITE CKSUM

errors: Permanent errors have been detected in the following files:

        rpool-hdd/vm-401-disk-0:<0x1>

disk is for an VM used as a mere repository for rsnapshot backup, so contain
many copy of the same files, with different and abunndant retention.
Is an addon disk for the VM, eg i can safely if needed umount it, even
detach it.


There's something i can do to repair the volue, possibly online? really i
have to backup it, destroy and restore from backup?!


Thanks.
