dumpe2fs − dump filesystem information
dumpe2fs [ −bfhV ] [ −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. | ||
|
−V |
print the version number of dumpe2fs and exit. |
You need to know the physical filesystem structure to understand the output.
dumpe2fs was written by Remy Card <card@masi.ibp.fr>, the developer and maintainer of the ext2 fs.
dumpe2fs is part of the e2fsprogs package and is available for anonymous ftp from tsx-11.mit.edu in /pub/linux/packages/ext2fs.
