Linux / Unix Command: dumpe2fs
Command Library

NAME

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.
