DUMPE2FS(8)                                                        DUMPE2FS(8)

NAME
       dumpe2fs - dump ext2/ext3/ext4 filesystem information

SYNOPSIS
       dumpe2fs [ -bfhixV ] [ -o superblock=superblock ] [ -o blocksize=block-
       size ] 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  filesys-
              tem.

       -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 created by
              e2image, using device as the pathname to the image file.

       -x     print the detailed group information block numbers in  hexadeci-
              mal format

       -V     print the version number of dumpe2fs and exit.

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