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 corrupted 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 corrupted 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.
