Do not partition the md device. It is not supported. You can run a
partition tool on it, but the kernel does not support partitions on md
devices at this time. It simply doesn't have device major/minor numbers
allocated to support that.
Use LVM or create a seperate raid for each mount you want.
After creating the raid partitions, go to the raid menu and setup the
raid, then when you come back, do nothing other than select what to use
the raid for and what filesystem to use, or that it should be an LVM
device (after which you go setup lvm).
