e2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
e2undo [ -f ] [ -h ] [ -n ] [ -v ] undo_log device
e2undo 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.
-f Normally, e2undo will check the filesystem superblock 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.
-h Display a usage message.
-n Dry-run; do not actually write blocks back to the filesystem.
-o offset
Specify the filesystem's offset (in bytes) from the beginning
of the device or file.
-v Report which block we're currently replaying.
