e2undo
E2UNDO(8) System Manager's Manual E2UNDO(8)
NAME
e2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
SYNOPSIS
e2undo [ -f ] [ -h ] [ -n ] [ -o offset ] [ -v ] [ -z undo_file ] 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.
-z undo_file
Before overwriting a file system block, write the old contents of the block to an undo file. This undo file can be used with
e2undo(8) to restore the old contents of the file system should something go wrong. If the empty string is passed as the undo_file
argument, the undo file will be written to a file named e2undo-device.e2undo in the directory specified via the E2FSPROGS_UNDO_DIR
environment variable.
WARNING: The undo file cannot be used to recover from a power or system crash.

e2undo was written by Aneesh Kumar K.V. (aneesh.kumar@linux.vnet.ibm.com)
