报错

mount: wrong fs type, bad option, bad superblock on 192.168.0.252/mnt/jamestest,
       missing codepage or helper program, or other error
       (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.

本地解决测试

mount -t nfs 192.168.0.252:/mnt/jamestest /mnt

所有k8s 节点需要安装nfs-utils并启动

yum install -y nfs-utils
ystemctl enable rpcbind
ystemctl start rpcbind
