Hah! That's funny. I just picked up a copy of "The Complete FreeBSD 4th
the other day. But haven't had an opportunity to read it yet. Guess I'd
better get to it. :)

Seems so. But if you've got much data, and don't have a DVD, or tape
magazine on it. You'll need to do the operation (likely) over NFS,
and likely requiring a couple of re-boots.
As I look at this (gmirror at sysinstall time) closer, it occurs to
me that it wouldn't be very difficult to implement response script
that asked questions for a basic gmirror setup that would encompass
all drives available (seen/understood) and offered to create:
and simply asked how big the slices should be made.
Just a thought.
Thanks again for the response.
