DUMPE2FS(8)                                                        DUMPE2FS(8)



NAME
       dumpe2fs - dump ext2/ext3/ext4 filesystem information

SYNOPSIS
       dumpe2fs [ -bfhixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device

DESCRIPTION
       dumpe2fs prints the super block and blocks group  information  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.

       -o superblock=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 corrupted filesystem.

       -o blocksize=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 corrupted filesystem.

       -f     force dumpe2fs to display a filesystem even though it may have some filesys-
              tem 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  created  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.
