Description of problem:
Create an nfs persistent volume and persistent volume claim, after the claim bound the volume, create a pod with this claim specified, the data on the nfs volume can not be viewed from the pod. The pod might not have successfully mounted the volume.

Version-Release number of selected component (if applicable):
Client Version: version.Info{Major:"0", Minor:"3+", GitVersion:"v0.3-9563-gb7caedeedb74f9-dirty", GitCommit:"b7caedeedb74f954e42d6c4bf957b0cdc5e3c3a5", GitTreeState:"dirty"}

How reproducible:
Always

Steps to Reproduce:
1. Create an NFS persistent volume
apiVersion: v1beta3
kind: PersistentVolume
metadata:
  name: nfs
spec:
  capacity:
    storage: 5Gi
  accessModes:
    - ReadWriteOnce
  nfs:
    path: /nfsshare
    server: 10.66.79.155


2. Create a claim
kind: PersistentVolumeClaim
apiVersion: v1beta3
metadata:
  name: nfsclaim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi


3. Create a pod that specifies the claim
kind: Pod
apiVersion: v1beta3
metadata:
  name: mypod
  labels:
    name: frontendhttp
spec:
  containers:
    - name: myfrontend
      image: nginx
      ports:
        - containerPort: 80
          name: "http-server"
      volumeMounts:
      - mountPath: "/usr/share/nginx/html"
        name: mypd
  volumes:
    - name: mypd
      source:
        persistentVolumeClaim:
          clainName: "nfsclaim"

4. After pod is created successfully, list files under /usr/share/nginx/html in the pod
cluster/kubectl.sh exec -p mypod ls /usr/share/nginx/html

Actual results:
After step 2: PV and PVC are bound
# cluster/kubectl.sh get pv          
NAME      LABELS    CAPACITY     ACCESSMODES   STATUS    CLAIM
nfs       <none>    5368709120   RWO           Bound     default/nfsclaim

# cluster/kubectl.sh get pvc
NAME       LABELS    STATUS    VOLUME
nfsclaim   map[]     Bound     nfs


After step 4: Nothing listed(an index.html is create on that volume before the pod mounts it), maybe the pod does not mount the volume

Expected results:
After step 4: Should see an index.html listed, which is prepared on the nfs volume.
