Remove uninitialized cow if snapshot creation fails
PATCH 1/1 Remove uninitialized cow if snapshot creation fails
Similar to the mirror log cleanup, snapshot cow also should be removed if the snapshot creation fails.
# dmsetup create --notable testvg-lvol1-cow # lvcreate -s -l1 -n lvol1 testvg/lvol0 /dev/testvg/lvol1: not found: device not cleared Aborting. Failed to wipe snapshot exception store. Remove new LV and retry. # lvs LV VG Attr LSize Origin Snap% Move Log Copy% lvol0 testvg -wi-a- 4.00M lvol1 testvg -wi--- 4.00M
Attached patch removes the incomplete COW LV if the snapshot creation fails.
A test script is also attached.
Thanks,
