You are in luck. I never did one before when I started too. I did a step by
step procedure that covers adding and removing drives... For centos 5.x,
with 4 drives.

This will take 2 drives into a raid 1, with LVM and all that.
IT adds a third drive as a hot spare incase one fails.
It adds a fourth as a standalone backup (good for a rync of the raid)
Just remember to wait for the drives to sync up before doing too much.
This is a step by step for newbs like me and is perfectly tailored for what
you need.
Let me know if you have any issues.
