SYNOPSIS
dumpe2fs
[
-bfhV
]
[
-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.
- -V
-
print the version number of
dumpe2fs
and exit.
BUGS
You need to know the physical filesystem structure to understand the
output.
