Mount point persistence with fstab

We should firstly identify the block device with dmesg:

dmesg | grep sd

[611156.2271561] sd 2:0:3:0: [sdd] Attached SCSI disk

Create a new partition table:

sudo fdisk /dev/sdd
o (to create a new / empty DOS partition table.)
n (to create a new primary ext3 partition.)
w (to write changes.)

Lets create the filesystem with:

mkfs.ext3 /dev/sdd1

Now grab the UUID of the partition with:

blkid /dev/sdd1

and then perform a test mount of the partition e.g.:

mkdir -p /mount/mountpoint

mount -t auto /dev/sdd1 /mount/mountpoint

and if all goes well - add our fstab entry in e.g:

echo 'UUID=1c24164-e383-1093-22225-60ced4113179  /backups  ext3 defaults  0  0' >> fstab

and reboot the system to test.
