Docker无法重新启动装载硬盘上的数据

我使用mount /dev/vdb /mnt/data在/mnt/data上挂载一个硬盘

更改默认的/etc/docker/daemon.json文件夹： /etc/docker/daemon.json

 { "graph": "/mnt/data/docker" } 

一切工作正常。

但在计算机重新启动后：docker守护进程无法重新启动

我得到这些错误：

 $ service docker start Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. 

和
