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.
