Oh noes, while starting a container, it failed cause of a corrupt quota file…
Starting container ... vzquota : (error) quota file is corrupted vzquota on failed  TASK ERROR: command 'vzctl start 114' failed: exit code 60
The fix is to remove it and rebuild it (this takes a long time, depending on the size of the container)
# this failed vzquota off 114 # delete the quota quota drop 114
We can rebuild the quota using
vzquota but that is done automatically if you restart the container :
# vzctl start 114 Starting container ... Initializing quota ...
The vzquota currently running is : (for reference)
/usr/sbin/vzquota init 114 -b 8388608100 -B 9227468900 -i 1600000100 -I 1760000100 -p /data/private/114 -e 0 -n 0 -s 0
Sit back and relax, cause this will take time.
