NAME
       dumpe2fs - dump filesystem information

SYNOPSIS
       dumpe2fs  [ -bfhixV ] [ -ob superblock ] [ -oB blocksize ]
       device

DESCRIPTION
       dumpe2fs prints the super block and blocks group  informa-
       tion for the filesystem present on device.

       dumpe2fs  is  similar to Berkeley's dumpfs program for the
       BSD Fast File System.

OPTIONS
       -b     print the blocks which are reserved as bad  in  the
              filesystem.

       -ob superblock
              use   the   block  superblock  when  examining  the
              filesystem.  This  option  is  not  usually  needed
              except  by a filesystem wizard who is examining the
              remains of a very badly corupted filesystem.

       -oB blocksize
              use blocks of blocksize bytes  when  examining  the
              filesystem.   This  option  is  not  usually needed
              except by a filesystem wizard who is examining  the
              remains of a very badly corupted filesystem.

       -f     force  dumpe2fs to display a filesystem even though
              it may have some  filesystem  feature  flags  which
              dumpe2fs  may  not  understand (and which can cause
              some of dumpe2fs's display to be suspect).

       -h     only display the superblock information and not any
              of the block group descriptor detail information.

       -i     display the filesystem data from an image file cre-
              ated by e2image, using device as  the  pathname  to
              the image file.

       -x     print  the detailed group information block numbers
              in hexadecimal format

       -V     print the version number of dumpe2fs and exit.

BUGS
       You need to know  the  physical  filesystem  structure  to
       understand the output.
