Output: mount: 文件系统类型错误、选项错误、10.103.23.10:/nfsfile 上有坏超级块、
       缺少代码页或助手程序，或其他错误
       (对某些文件系统(如 nfs、cifs) 您可能需要
       一款 /sbin/mount.<类型> 助手程序)

       有些情况下在 syslog 中可以找到一些有用信息- 请尝试
       dmesg | tail  这样的命令看看。

解决版本：在worker节点行安装nfs-utils

Output: mount.nfs: access denied by server while mounting 10.103.23.10:/nfsfile
