You have sort of painted yourself into a corner here. It is hard to get system support for something the system is designed to handle that you have done outside of it. You already implemented a solution that isn't working, and now your data is stuck on it. My recommendation is to copy your data off onto something else temporarily, reconfigure through the system, and then migrate it back once your original issue is fixed.
In the future, when you encounter something not working,
1. See if a ticket exists in http://svn.linuxmce.org
which matches your problem, if not, create one. Be as specific as you can describing the environment and circumstances.
2. See if you can get help either on the forum or in IRC. This way we can get a better idea of what a solution might be to close your ticket and fix it for everyone. Most of us do not deal with RAID on our production or development systems, we just use NAS bricks... so we cannot reproduce errors you are encountering.
If you go hammering away at it on your own, we don't know something is wrong... and then you end up here... on your own
