Hey Aurf,
Not sure, but this google cache of a 5.x set up might explain and help 
you out.
If your problem is taking a drive out and the other not booting you may 
not have allowed the initial snyc of the drives to complete...something 
I would heartily suggest
https://webcache.googleusercontent.com/search?oe=utf-8&rls=org.mozilla%3Aen-US%3Aofficial&client=firefox-a&gbv=1&sei=yRCGT_7MCqLi0QH6r9DWBw&hl=en&q=cache:5QBSeA1JCZsJ:http://www.bobhoffman.com/test.html?a=17+bobhoffman.com+cat+/proc/mdstat&ct=clnk

that page shows how a raid 1 mirror was set up with 2 drives and one 
spare. It goes over taking one out, adding a new one, etc....and even 
making sure that grub is working on both drives.

not sure exactly which issue out of all those in that link you posted 
you are having though.
