Zdenek Kabelac 40e6176d25 snapshots: fix incorrect calculation of cow size ... Code uses target driver version for better estimation of max size of COW device for snapshot. The bug can be tested with this script: VG=vg1 lvremove -f $VG/origin set -e lvcreate -L 2143289344b -n origin $VG lvcreate -n snap -c 8k -L 2304M -s $VG/origin dd if=/dev/zero of=/dev/$VG/snap bs=1M count=2044 oflag=direct The bug happens when these two conditions are met * origin size is divisible by (chunk_size/16) - so that the last metadata area is filled completely * the miscalculated snapshot metadata size is divisible by extent size - so that there is no padding to extent boundary which would otherwise save us Signed-off-by:Mikulas Patocka <mpatocka@redhat.com>		2014-02-26 14:25:09 +01:00
