nfs.deployment.yaml：

        volumeMounts:
          - mountPath: /exports
            name: mypvc
      volumes:
        - name: mypvc
          persistentVolumeClaim:
            claimName: nfs-data

exportfs是指什么？我该如何进一步诊断？

在nfs窗格中，不太确定为什么要导出/吗？

[root@nfs-685944f556-r2pjr /]# cat /etc/exports
/exports *(rw,fsid=0,insecure,no_root_squash)
/ *(rw,fsid=0,insecure,no_root_squash)

Answer 1

不太清楚为什么要导出/

这是通过run_nfs.sh脚本完成的，并带有两个参数：

/bin/bash /usr/local/bin/run_nfs.sh /exports /

图像gcr.io/google_containers/volume-nfs存在问题，因此建议改用jsafrane/nfs-data图像

请参见相应的github discussion
