dumpe2fs - dump filesystem information
dumpe2fs [ -bfhixV ] [ -ob superblock ] [ -oB blocksize ] device
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.
-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.
You need to know the physical filesystem structure to understand the
output.
