How do I mount the filesystem (disk partition) using the filesystem label on the ext3/ext4 file system located on USB disk or hard disk under Linux operating systems?
The e2label command will display or set the filesystem label. The mount command has the option to mount partition that has the specified label. To see your current label type the following command:
# e2label /dev/sdc1
Sample outputs:
seagate_2tb_usb
Syntax: Mount Command With Label
The syntax is as follows:
mount -L label_name_here /path/to/mount/point
To mount the /dev/sdc1 using the seagate_2tb_usb label at /media/usb, enter:
# mkdir -p /media/usb
# mount -L seagate_2tb_usb /media/usb
# df -H
Sample outputs:
Filesystem Size Used Avail Use% Mounted on
/dev/md0 127G 902M 120G 1% /
tmpfs 1.1G 0 1.1G 0% /lib/init/rw
udev 1.1G 267k 1.1G 1% /dev
tmpfs 1.1G 0 1.1G 0% /dev/shm
/dev/md2 1.6T 81G 1.5T 6% /data
/dev/mapper/cryptvg-mybackup
635G 48G 555G 8% /securebackup
/dev/sdf1 2.0T 858G 1.1T 46% /media/usb
Please note that my actual device name is /dev/sdf1. Feel free to replace actual label names and mount point as per your requirements.
Update /etc/fstab File
You can update the /etc/fstab file as follows to mount it automatically using the disk label:
LABEL=seagate_2tb_usb /media/usb ext3 defaults 0 0

mount /dev/disk/by-label/SOMEDISKNAME /mnt/foobar
or put this in fstab
LABEL=SOMEDISKNAME /mnt/foobar vfat users,uid=1000,gid=users,umask=0002,utf8=true 0 0
How do i find the Label if the disk failed? We have no option from the /etc/fstab to identify the disk/partiotion information!!
I am on ubuntu 14.04 LTS. The e2label works fine.
However I am not able to see the device in Nautilus files, under devices.
