Attempting and failing to use NFS storage for Kubernetes volumes.

persistentvolumeclaim is unable to bind to already created persistentvolume, see below

Creating persistentvolume

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteMany
  nfs:
    server: 192.0.2.100
    path: "/nfsshare"

Creating persistentvolumeclaim

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi

Event logs for the persistentvolumeclaim shows

kubectl get events:
"provisionable volume plugin matched"

Any ideas what might be stop k8s to bind the two?
