DUMPE2FS(8)		    System Manager's Manual		   DUMPE2FS(8)

NAME
       dumpe2fs	- dump filesystem information

SYNOPSIS
       dumpe2fs	[ -bfhixV ] [ -ob superblock ] [ -oB 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.

       -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 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 e2im-
	      age, 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.
