What's the right way to set up>2TB partitions for raid1 autoassembly?   I don't need to boot from this but I'd like it to come up and mount automatically at boot.

disks 2TB and up have to be formatted as GPT rather than MBR, so old MBR tools like fdisk are useless.  use parted

I would build a LVM vg with the multi-terabyte volumes, using lvm mirroring, and then create an XFS lv on the vg ....     xfs seems 100% stable and high performance on centos6

What I'm looking for is the way to make md raid autodetect and assemble on boot. With fdisk, you would set the partition type to FD for that, but I don't see an equivalent in parted.
