  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.
