ON Centos 5, using GPARTED I created partitions for filing systems ext3
and ext4. 4 primary and unlimited (except by space) extended partitions.
That suggests those partitions are not GPT but old fashioned M$DOS
If it is old fashioned MSDOS, you can have four total primary and extended,
not four primary plus extended. An extended partition then provides a
container for further logical partitions.
I encrypted some of those partitions.
The 'blkid' command produces a list of UUIDs for those partitions.
A few examples:-
/dev/sda5: LABEL="a5u" UUID="3cbc7570-30b8-4970-a0df-a9a9602770d0" TYPE="ext4"
/dev/sda2: UUID="e954fbaa-dc51-46dc-a352-cceb439080e5" TYPE="crypt_LUKS"
/dev/ram0: UUID="49b98b86-116a-469b-b6de-a157bb0a12dd" TYPE="ext2"
/dev/sda1: LABEL="d6sys" UUID="cd632820-0701-4a6a-b329-6798b6a29966" TYPE="ext3" SEC_TYPE="ext2"
LUKS provides a UUID, so being encrypted isn't a barrier to having a UUID.
