Replay an undo log for an ext2/ext3/ext4 filesystem
SYNOPSIS
e2undo
[
-f
]
[
-h
]
[
-n
]
[
-v
]
undo_log device
DESCRIPTION
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.
OPTIONS
- -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.
