I just now realized that you have fakeraid (dmraid). That is very 
dangerous, because if MB dies, you might need to find another one with 
same chipset to make it work. On the other hand, Linux software RAID 
(mdadm). That way your RAID will work on any MB.

So I also recommend William Warren's suggestion to convert as soon as 
possible. You can even use "RAID 10 - far" to gain 2 x read and 1 x 
write speed of normal disk while mirroring.
