To make a long story short, I'd abandon the work you've done so far if
I were you, and start over using softraid(4) instead. (man softraid,
man bioctl, man disklabel).
There are some drawbacks to using softraid at the moment - for example
you can't boot from a softraid partition and (IIRC) you can't mirror
the root partition (but see man daily for mentions of /altroot).
But using RAIDframe (raid(4)) as you're doing now is really a pain in
the ***, even if it undoubtedly will do everything you want when properly
set up. It is pathetically tricky to set it up to raid the root partition
and to automount it at boot, but it is doable. Don't know of any up-to-
date guides on how to do it though.
I'm off to bed now, but if you decide to persist with your chosen
path and nobody else have given you a hand by then, I'll help you
tomorrow. :-)
