    dumpe2fs

    
    
    

    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.
