[linux-lvm] add mirror to already existing LV?

[Don Buchholz <buchholz@easystreet.net>]

  I have Fedora 8 system with operating system installed on a small
(18GB) hard disk.  A second disk (320GB) is being added to hold
user data.  Now that there is a second disk, I would like to alter
the existing LVs so they have mirrors.  Is this possible?
  I couldn't find anything that looked promising on the lvchange(8)
man page.
