Hi @alexus
Assuming you followed the exact directions in the documents... Sometimes the cluster may not come up just for whatever reason.

What I have found you need to do is completely clean up, shut down and prune all the mounts and everything and then try again.
We've had several users have the same experience and this is how they got it to work.
