This is still the same linux on the server? Because mdstat says no raid 
personalities are installed. Either linux has changed or you've got 
hardware raid. in which case you'll need to read up on the motherboard 

I'm not sure what they're called, but try "insmod raid1x" I think it is. 
Could be raid0x. If that loads the raid0 driver, cat /proc/mdstat should 
list raid0 as a personality. Once that's there, mdadm may be able to 
start the array.

Until you've got a working raid driver in the kernel, I certainly can't 
help any further. But hopefully reading the mobo manual might help. The 
other thing to try is an up-to-date rescue disk and see if that can read 
the array.
