NAME

   e2undo - 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.
