Restore a 4-node cluster based on only the data directories

I had a 4-node cluster, running on Kubernetes (Version v1.0.6). Can I recreate that cluster on a new host, using the data directories? It would seem now, because although the Web UI shows me all four nodes, the correct capacity and so on, it doesn’t actually connect to show the rest of the data.

Log shows messages such as:

Is there any way I can get my data back?

Wow. It suddenly come online!
