上面的问题告诉我们docker容器挂载的磁盘忙
相同的问题经验解决：
umount /dev/cdrom /mnt ，也出现过 device or resource busy
解决方案就是卸载挂载目录：umount /dev/cdrom 或者 umount /mnt
同理，只需要将容器的挂载目录卸掉就行，我这么做了，也成功了。我想应该就是这个问题。
[root@hdp-gp-dk02 ~]# umount /var/lib/docker/devicemapper/mnt/01ea65845e4547be24bc3db0bc3b424faf52b8a0534eb525aa829dd9fd6081c2
[root@hdp-gp-dk02 ~]# docker start 01ea65845e45
01ea65845e45
[root@hdp-gp-dk02 ~]# docker ps -a

重新启动之后的容器成功了。
