"failed-disk" directive.
As an example, you can check out "Method 2" of the "Root filesystem
on RAID" section (although in your case it's /home so life is a little
easier) at http://www.linuxdoc.org/HOWTO/Software-RAID-HOWTO-4.html#ss4.12
Jakob: how do you feel about a section that covers the "mirroring of
currently existing filesystem" case? mirroring /home when a
spare drive becomes available could be quite useful :)
