Debugging issues with the rook ceph storage provisioner

My pod is stuck in the pending state. When i run kubectl describe pod <pod name> I see the following in the Events section:

  Warning  FailedScheduling  5m48s (x3 over 5m49s)  default-scheduler   pod has unbound immediate PersistentVolumeClaims

Running kubectl describe pvc <pvc name> shows that the volume claim is waiting on the ceph.rook.io/block storage provisioner.
