Hello, one vm failled backup:

now I'll try again, but could get same result EDIT :failed again:

any clues on what causes this:
Code: 
tar: ./rsnapshot/hourly.0/localhost/fbc/linux-install/13-do-on-most-systems: Cannot stat:
Structure needs cleaning

this is a LXC system so if fsck should be done - could someone give a clue on where to do that?

you can use pct for a fsck
Code: 
pct fsck <vmdi>

see
Code: 
man pct
for more details
 
fsck done, backup fails again:
Code: 
# pct fsck 2446 --device mp0
fsck from util-linux 2.29.2
/dev/rbd3: clean, 245759/16384000 files, 32960256/65536000 blocks

# pct fsck 2446 --device mp0 --force 1

more info soon.
 
- bad files are on 1ST disk. 2ND disk is a much larger disk for data.
- I turned off backup of 2ND disk to speed up the process.
- the backup works:
Code:

INFO: Finished Backup of VM 2446 (00:00:54)

TASK OK
now I do not understand why the fails only when both disks are backed up.

without doing a fsck , I just tried backing up again and that worked.
