why would you need to hide the hardware details from md ?
The way i do it is to md 2 disks together into a pair, and
then pvcreate it and add it to my VG. That way i can get
more and more disks into the system. I have thought about
creating 2 VG's, and then run md ontop of that, but it's more
work, as you would have to resize 2 LV's, and besides, a harddisk
failure might trash one of your VG's. Meaning more repair work.
