On our machines with software raid, I usually use all available disks to
create (small) root filesystem on raid1 - which is 2, 3, 4, 5, or even 8
on one machine.  There's no special restriction on number of mirrors in
a raid1 set.  You create raid1 array on top of N disks exactly the same
as you create it on 2 disks.
