I shutdown the containers and made a backup: # rsync -HSav /vz/private /vz/private_backup Some time later I shutdown all containers again and restored a backup: # rsync -HSav --delete /vz/private_backup/101 /vz/private/ When I start the container, I get this output: ... 71: 880640.. 912689: 1734656.. 1766705: 32050: 1701888: 72: 912690.. 915455: 1766706.. 1769471: 2766: 73: 915456.. 923391: 1771520.. 1779455: 7936: 1769472: last,eof /vz/private/101/root.hdd/root.hdd: 48 extents found --- filefrag -vs finished --- Adding delta dev=/dev/ploop25334 img=/vz/private/101/root.hdd/root.hdd (rw) Mounting /dev/ploop25334p1 at /vz/root/101 fstype=ext4 data='balloon_ino=12,' Container is mounted Adding IP address(es): 10.1.0.101 Setting CPU units: 1000 Container start in progress... What does this mean? Is this something to be worried about?
