k8s中NFS存储 的PVC和PV的挂载不到问题

K8S挂载pv不成功的原因

1. 各Node节点上没有安装NFS的软件包,需要先安装nfs-utils
2. PV声明时,如下, accessMode 和PVC申请的accessMode不匹配,一般ReadWriteOnce,ReadWriteMany,ReadWriteOnly.
3. 容量大小不一致, 比如下面的配置是5G,那么申请的必须小于5G才行

4. apiVersion: v1
   kind: PersistentVolume
   metadata:
       name: nginx7
   spec:

       persistentVolumeReclaimPolicy: Recycle
   #    storageClassName: slow
       nfs:
