NAME¶

SYNOPSIS¶

DESCRIPTION¶

Note: When used with a mounted filesystem, the printed information may be old or inconsistent.

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).

-g

display the group descriptor information in a machine readable colon-separated value format. The fields displayed are the group number; the number of the first block in the group; the superblock location (or -1 if not present); the range of blocks used by the group descriptors (or -1 if not present); the block bitmap location; the inode bitmap location; and the range of blocks used by the inode table.

-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.
