现象
由于主机磁盘空间不足，但是经过查询，docker并没有占用很大空间，也就是说du和df查出来的空间差异很大，这可能是deleted的文件很多导致，只能重启docker或重启主机了。
这里，我强制重启docker后，就不能启动容器，报错：
1 2 3 | [root@mdw ~]# docker start a03d68768b33 Error response from daemon: failed to create task for container: task a03d68768b33663cd8ce952233ef7e2e23a18fdcecfb542988bb3b65c5b03b94: already exists Error: failed to start containers: a03d68768b33 |
原因
原因：容器未安全退出
解决
解决方式一
需要杀掉moby的进程：
