NAME
dumpe2fs - dump ext2/ext3 filesystem informationSYNOPSIS
dumpe2fs [ -bfhixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] deviceDESCRIPTION
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.
- -o superblock=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.
- -o blocksize=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.AUTHOR
