Unless you want to boot from the new disks, you should be able to use GPT on them. Are you sure you're using GRUB legacy?

Yes, Everything worked out fine. I left 3M at the beginning just in the off chance I would want to place grub2 boot code on the array and left 100M at the end to insure painless disk replacement. Created a 2.9T GPT partition using gdisk, then the mdadm array, all worked great. (it did take hours for the initial sync and bitmap creation for the 3T array -- 237 minutes if I recall correctly) Absolutely no problems though. -- David C. Rankin, J.D.,P.E.
