e2label - Man Page

• Change the volume label on a specific ext partition: e2label /dev/sda1 "label_name"

tldr.sh

e2label device [ volume-label ]

e2label will display or change the volume label on the ext2, ext3, or ext4 file system located on device.

If the optional argument volume-label is not present, e2label will simply display the current volume label.

If the optional argument volume-label is present, then e2label will set the volume label to be volume-label. Ext2 volume labels can be at most 16 characters long; if volume-label is longer than 16 characters, e2label will truncate it and print a warning message.  For other file systems that support online label manipulation and are mounted e2label will work as well, but it will not attempt to truncate the volume-label at all.

It is also possible to set the volume label using the -L option of tune2fs(8).
