List all UUIDs

Use blkid command-line utility to locate/print block device attributes:
$ sudo blkid
Sample output:

/dev/sda1: TYPE="ntfs" UUID="A0F0582EF0580CC2"
/dev/sda2: UUID="8c2da865-13f4-47a2-9c92-2f31738469e8" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda3: TYPE="swap" UUID="5641913f-9bcc-4d8a-8bcb-ddfc3159e70f"
/dev/sda5: UUID="FAB008D6B0089AF1" TYPE="ntfs"
/dev/sdb1: UUID="32c61b65-f2f8-4041-a5d5-3d5ef4182723" SEC_TYPE="ext2" TYPE="ext3"
/dev/sdb2: UUID="41c22818-fbad-4da6-8196-c816df0b7aa8" SEC_TYPE="ext2" TYPE="ext3"

How do I use UUID to update /etc/fstab file?

Simply use following syntax:

UUID={YOUR-UID}    {/path/to/mount/point}               {file-system-type}    defaults,errors=remount-ro 0       1

Open /etc/fstab:
$ sudo vi /etc/fstab
Append line as follows:

UUID=41c22818-fbad-4da6-8196-c816df0b7aa8  /disk2p2      ext3    defaults,errors=remount-ro 0       1

Save and close the file. To mount new partition immediately using /etc/fstab type:
$ sudo mount -a
