Software RAID

[Don Calfa]

I'm in the process of  testing Linux Software RAID.  My goal is to take 
an array in one distro and access it from other distro's.  Where is the 
best site for info?  I currently have the array built with RH9, plan to 
kill (not the array) and try MDK9.1, Gentoo, Debian (woody), and Slack. 
 I've found stuff on linas.org but I need more rudimentary info.

I eventually will have a distro up that will use it and I need the 
recovery practice.
Thanks
