# Auto remount the volume.
115+
116+
Since the device name can change with each reboot, the more reliable method to remount the volume is to use the UUID. The UUID of the device can be retrieved like so:
117+
118+
`sudo blkid /dev/sdb`
119+
120+
After getting the device UUID, add the following entry to _/etc/fstab_ file:
121+
122+
`UUID=<uuid> /mnt/col5 ext4 defaults,nofail,noatime 0 2`
