you need GPT to partition devices larger than 2TB, regardless of the parittion size.
me, I use parted....
# parted /dev/sdc "label gpt" # parted /dev/sdc -a none "mkpart primary 512s -1s"to make a single full disk partition that starts at sector 512, which is 256K bytes, which is usually a decent boundary for SSDs, large raids, and other such devices.
Large drives often have 4k sectors - don't you want a 1M offset to make sure the partition start is aligned? Gparted seems to do that by default. Also, is it possible to make the raid auto-assemble at boot like smaller ones do? I had to put an ARRAY entry into /etc/mdadm.conf with the devices but I think someone advised doing "set <partition number> raid on" in parted.
