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