e2label

change ext filesystem labels

TLDR

Display the current volume label

$ sudo e2label [/dev/sda1]

Change volume label

$ sudo e2label [/dev/sda1] "[label_name]"

Clear the volume label

$ sudo e2label [/dev/sda1] ""

e2label changes or displays the filesystem label on an ext2/ext3/ext4 filesystem. Labels provide human-readable names for filesystems and can be used to mount filesystems by label instead of device name, which improves portability when device names change.If no label is specified, the current label is displayed. Labels are particularly useful in /etc/fstab entries, making system configuration more resilient to device renaming after hardware changes.

CAVEATS

Labels are limited to 16 characters and are silently truncated if longer. e2label is a thin wrapper around tune2fs -L, so the two are interchangeable. The filesystem may be mounted while the label is changed, but the new label is only picked up by udev and /dev/disk/by-label after the next scan. Part of the e2fsprogs package.
