Thanks for all the suggestions. GPT labels are what came out of the box.

That's another possibility to add to the list - I'll probably 
investigate XFS first. I don't need to boot from these arrays - I 
already have a system disk and mirror disk in place.

If the truth be told, I am using Scientific Linux 4.3 but I didn't want 
to be told to go elsewhere (as this list has proved to be very helpful 
to me in the past)

Thanks again
