Newcomer's question about existing software raid

[Peter Humphrey]

Hello list,

I've just used the 9.10 standard installation CD to install Kubuntu in some 
spare space on an IDE drive, and now I want to mount one of the existing 
mdraid partitions on /home/<user>/common. I've googled for advice but I only 
see how to install on a new mdraid partition, not how to mount one that's 
there already.

I've installed mdraid, and the mdraid.conf file is written, apparently 
correctly, but I still get "/dev/md2 does not exist" when I attempt to mount 
it.

Would someone please point me to where I can find the right advice?

Thanks.
