DUMPE2FS(8) System Manager's Manual DUMPE2FS(8)NAMEdumpe2fs - dump filesystem informationSYNOPSISdumpe2fs [ -bfhixV ] [ -ob superblock ] [ -oB blocksize ] deviceDESCRIPTIONdumpe2fs 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.BUGSYou need to know the physical filesystem structure to understand the output.AUTHORdumpe2fs was written by Remy Card <Remy.Card@linux.org>.AVAILABILITYdumpe2fs is part of the e2fsprogs package and is available from http://e2fsprogs.sourceforge.net.SEE ALSOe2fsck(8), mke2fs(8), tune2fs(8) E2fsprogs version 1.32 November 2002 DUMPE2FS(8)
