 DUMPE2FS(8)                                           DUMPE2FS(8)
 
 
 
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.
