Actually, it has been done, and it has been working for quite some time,
in several different versions even :)  Take a look at the FreeBSD
Handbook:

http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/

Look at chapter 16, "Storage", and especially 16.5, "RAID".  After that,
look at chapter 17, "The Vinum Volume Manager".  Those will probably
contain most of the information that you need :)

There is also an excellent separate article about Vinum at

http://www.FreeBSD.org/doc/en_US.ISO8859-1/articles/vinum/

Hope that helps!

G'luck,
Peter

Hey, out there - is it *you* reading me, or is it someone else?
