NAMEe2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
SYNOPSISe2undo [ -f ] undo_log device
DESCRIPTIONe2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesystem found on device. This can be used to undo a failed operation by an e2fsprogs program.
- Normally, e2undo will check the filesystem UUID and last modified time to make sure the undo log matches with the filesystem on the device. If they do not match, e2undo will refuse to apply the undo log as a safety mechanism. The -f option disables this safety mechanism.
