Yes, it only works for mirrors, since I thought it doesn't really matter if a
mirror is properly initialized, since the user need to put data into the
mirror for it to be useful anyway. The same goes for RAID-5 I guess, but I
was not sure if it might trigger some weird behaviour since parity would not
match if reading the volume. I will test out a small modification I made,
which removes the need to run 'gvinum start' on the raid5 plexes.
