After motherboard swap, mdadm RAID 6 fails to assemble

Hello all. I recently upgraded my home server by installing a new Xeon e3-1270v3 and Supermicro X10SAT board. Installation was simple and I reconnected my controller card, a LSI 9211-8i. When I booted the array would not mount. I tried to stop and reassemble the array but was met with this:

root@PreciseServer:~# mdadm --assemble --scan --force -v /dev/md0

mdadm: /dev/md0 assembled from 3 drives - not enough to start the array.

The array is supposed to be ten drives in a RAID 6. I did not partition the drives when I created the array and have been growing the array by adding whole disks as I've gone. Can someone help me understand what happened? Even better, could someone please help me correct the problem so I can get my array running again?

Thanks so much for your time!
