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 mechanism.
- Display a usage message.
- 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.
- Report which block we're currently replaying.
