e2label - how to label a filesystem in Linux |
Description
In Linux, labelling a device specifically will make the system more robust because adding or removing a SCSI disk changes the disk device name but not the filesystem volume label.
To check if a volume label exists on a device in Linux:
# e2label /dev/sda6
/1 <=== LABEL exists
# e2label /dev/sdb3
<=== NO LABEL exists
To label a device:
# e2label /dev/sdb3 NODE0000
Update /etc/fstab to use the volume label instead of the device name:
# grep NODE000 /etc/fstab
#/dev/sdb3 /db2fs/bculinux/NODE0000 ext3 noauto 0 0
LABEL=NODE0000 /db2fs/bculinux/NODE0000 ext3 noauto 0 0
|
Example
e2label /dev/sdb3 NODE0000 |
