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 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 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.
