使用PV和PVC的Kubernetes NFS存储

我在VirtualBox中运行了一个3节点集群，我试图使用PV和PVC创建一个NFS存储，但似乎我做错了什么

我有以下资料：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: redis-pv
  labels:
    type: nfs
spec:
  capacity:
    storage: 100Mi
  volumeMode: Filesystem

    - hard
    - nfsvers=4.1
  nfs:
    path: /redis/data
    server: 192.168.56.2 #ip of my master-node

            memory: 100Mi
        volumeMounts:
        - name: data
          mountPath: "/redis/data"
        ports:
        - containerPort: 6379
      volumes:
      - name: data
        persistentVolumeClaim:
          claimName: redis-pvc

我已经在我的所有节点中安装了

nfs common

每当创建PV、PVC和POD时，POD不会启动，我得到以下信息：

apiVersion: v1

以下是kubectl get pv、pvc的状态
