Build from scratch, restore from backup.
Thanks for your advice, thats the way I have gone.
Also: start a new thread for a new question, and you may want to try a more appropriate list - this one is 'debian-isp'; maybe 'debian-users' would be better.
I thought this list was appropriate as raids concerns the people that monitor this list, more so then debian-users. But never the less, i already have asked on that list as well. :)
