       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

解决办法:

所有节点安装nfs utlis

[root@k8s-node1 ~]# yum install nfs-utils -y

查看pod状态

[root@k8s-01 ~]# kubectl get pod -n nfs -o wide
