Thanks David, I'm sure that's good advice. I don't need to do that.  At the
moment,
it looks possible that I will be moving from a Supermicro server to a Dell.
I'm hoping
to be able to boot FBSD using the virtual disk on the Dell, configure the
hard drives,
and then use ZFS send/recv to replicate one server to the other.  It's
unclear if
the data center will provide me with the necessary access. Fingers crossed.

I always put the 'boot laoder stuff' on all the disks in the mirror, so the
machine can always boot.
