Bug Report

What happened: I have deployed rook-operator with helm chart and very basic cluster and block-storage pool from doc. When i created PVC, PV was created, but can not be mounted to a pod. I have this:

Unable to mount volumes for pod ***": timeout expired waiting for volumes to attach/mount for pod "***". list of unattached/unmounted volumes=[data]

I can see that volume was successfully created in operator logs

What you expected to happen: Volume mounted to a pod

How to reproduce it (minimal and precise): Deploy rook-alpha/rook with helm Create Cluster as described in quickstart Create Blockstorage Pool as described in quickstart Create SC for this Pool Create PVC
