在一台新机子上面，docker处理完lvs数据卷之后，启动docker服务时，出现了启动失败，失败信息如下：
[root@hxin221 ~]# systemctl status docker
● docker.service - Docker Application Container Engine

总的来说就是：
Error starting daemon: error initializing graphdriver: devmapper: Base Device UUID and Filesystem verification failed: devicemapper: Error running deviceCreate (ActivateDevice) dm_task_run failed
好吧，这个错误，之前没有遇到过，踩了很多坑，最终，想了想，莫非这台机子早先时候已经装了docker，然后旧数据导致的？
于是乎，就抱着试试看的目的，执行了如下操作：
[root@hxin221 ~]# rm -rf /var/lib/docker/*
没错，清除了docker的数据，由于是新机子，我也没有做什么备份处理，其他小伙伴如果又遇到的话，记得先备份数据。
于是，重启服务
[root@hxin221 ~]# systemctl restart docker
OK，问题不大，解决了。
以上
