centos7启动docker失败

Question

问题：根据官方文档在centos7上安装启动docker失败

命令：systemctl start docker

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

我的解答思路和尝试过的方法 ：通过dockerd --debug查看error提示： [graphdriver] prior storage driver devicemapper failed: Device is Busy

我想要达到的结果：正常启动起来
