Once array has been created, you cannot remove disk. Removing one disk from
Raid 5 set will cause array to become degraded, removing 2 disks will fail the
virtual drive with loss of data. If array is not in use or you don't care about
data you can break the raid set and create new. Sun's ZFS file system is more
fault tolerant.
