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. -- Les Mikesell lesmikesell at gmail.com
