[NTLUG:Discuss] Splitting mirrors in MD

[Johnie Stafford]

I am finally going to upgrade my old RH9 system. I currently have all
of my filesystems mirrored with md. I'm going to do a fresh install of
either CentOS or Fedora but I want to split the mirrors before I do
the upgrade so that I can get to the old filesystems in case I forget
to back something up that I need. 

The problem is that I can't figure out how to split the mirrors with
md. 

Anybody know how to do it?
