You need to use the e2label command to set a text label to your disk drive partitions and then refer to them in the /etc/fstab file. The e2label command must be run as root user. Normal users can not modify partition label for security reasons.
Syntax
Use the following syntax to display or change the filesystem label on the ext2, ext3, or ext4 filesystem located on device.
e2label /dev/device e2label /dev/device new-label-name-here |
Label limitations
Ext2 filesystem labels can be at most 16 characters long; if new-label-name-here is longer than 16 characters, e2label will truncate it and print a warning message on screen.
View the label of partition
To see the label of partition called /dev/sda5, type:
e2label /dev/sda5 |
Sample outputs:
Modify partition labels / Change disk name
To add or change the label of partition /dev/sda1 to “Webserver”, enter:
$ sudo e2label /dev/sda1 Webserver
OR
# e2label /dev/sda1 Webserver
To verify new changes, type:
# e2label /dev/sda1 Webserver
Mount file system by label at Linux server boot time
The /dev/sda1 partition can be mounted by label at server boot time at /wwwdata location. Edit the /etc/fstab file, enter:
$ sudo vi /etc/fstab
Set or update it as follows:
LABEL=Webserver /wwwdata ext4 defaults 1 2
Save and close the file. You can also use the mount command as follows:
mount -L label_name_here /path/to/mount/point |
