I was upgrading my Hyper V cluster from 2008R2 to 2012R2 and disaster has hit.
I built my second cluster, with one of a three node cluster and an older server everything went really well up until the point of of "copy cluster roles" from my old cluster to my new cluster.
A couple VMs came over ok but the rest all failed. I can still have all the VHDs and and the snapshots (checkpoints) so I removed the failed roles and started recreating them all was going fine and then the cluster lost access to the storage although I was able to see it at C:\clusterstorage and still can.
My question to start with is what is my best move forward? as I said I have all vhds and snapshots available.
