E2UNDO(8)E2UNDO(8)NAMEe2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
SYNOPSISe2undo [ -f ] [ -h ] [ -n ] [ -v ] undo_log device
DESCRIPTIONe2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesysâ
tem 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.
