E2LABEL(8) System Manager's Manual E2LABEL(8)NAME
e2label - Change the label on an ext2/ext3/ext4 filesystem
SYNOPSIS
e2label device [ new-label ]
DESCRIPTION
e2label will display or change the filesystem label on the ext2, ext3, or ext4 filesystem located on device.
If the optional argument new-label is not present, e2label will simply display the current filesystem label.
If the optional argument new-label is present, then e2label will set the filesystem label to be new-label. Ext2 filesystem labels can be
at most 16 characters long; if new-label is longer than 16 characters, e2label will truncate it and print a warning message.
It is also possible to set the filesystem label using the -L option of tune2fs(8).

DUMPE2FS(8) System Manager's Manual DUMPE2FS(8)NAME
dumpe2fs - dump ext2/ext3/ext4 filesystem information
SYNOPSIS
dumpe2fs [ -bfhixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device
DESCRIPTION
dumpe2fs prints the super block and blocks group information for the filesystem present on device.
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).
-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.
