I don't think that we will ever know. Have you tried starting the cluster group (Get-ClusterGroup 'cluster group' | start-clustergroup;)? If it starts, you're good. If not, you should have some messages in the cluster log about why it wasn't started. Also, if it does start, I'd suggest moving it around using Move-ClusterGroup -Node ... to each of the nodes in the cluster that you'd expect to be able to own it.
