Simple mirroring at the disk level seems to work fine; it's when you get
into creating RAID-5 volumes that everything starts to come off the
wheels. It really wants to have whole disks dedicated for whatever
you're doing; while you can configure RAID volumes against partitions,
you're asking for trouble if you do.

I'd just come off of a gig involving a lot of VxVM work, so I didn't see
anything weird about RAIDing partitions instead of whole disks.
Apparently all the online Linux folks I talked to thought that was
really strange. I even had one guy tell me that I was doing it
completely wrong (even though nothing in the docs suggested otherwise).
