After the OS was installed, I then used parted to create the gpt label on the large array and created the filesystem on it. On another system, I really needed the ports on the 3ware for the array so I installed a pair of 160gig drives using a cheapo dual port SATA card and used software RAID 1 on those two drives for the OS install. After the system was installed, I then used parted to create the GPT label on the large array and created the filesystem on it. If you go back through the list archives a bit, you'll see a bunch of very useful information from a couple of months ago where a number of people offered excellent tuning suggestions. If you get stuck, shoot me some email off list and I'll see if I can give you a hand. Cheers,
