On a new machine, after Docker finishes processing the LVS data volume, the boot failure occurs when the Docker service starts, and the failure message is as follows:

[[email protected] ~]# systemctl status Docker docker.service-docker application Container Engine loaded:loaded  (/usr/lib/systemd/system/docker.service; enabled; vendor preset:disabled) Drop-in:/usr/lib/systemd/system/docker.service.d└─flannel.conf active:failed (result:exit-code) since Tue 2018-07-24 14:06:15 CST; 4s ago docs:https://docs.docker.com process:28723 execstart=/usr/bin/dockerd $DOCKER _network_options $DOCKER _networ K_options $DOCKER _storage_options (code=exited, status=1/failure) Main pid:28723 (code=exited, status=1/failure) Memor y:412.0k CGroup:/system.slice/docker.servicejul 14:06:14 hxin221 systemd[1]: Starting Docker application Container Engine ...

In general it is:

Error starting Daemon:error initializing Graphdriver:devmapper:Base Device UUID and Filesystem verification Failed:dev Icemapper:error running Devicecreate (activatedevice) Dm_task_run failed

  

Well, this mistake, never encountered before, stepped on a lot of pits, and finally, think, is this machine has been installed in the previous time Docker, and then the old data caused?

So, with the aim of trying, the following actions are performed:

[Email protected] ~]# rm-rf/var/lib/docker/*

Yes, the data is removed from the Docker, because it is a new machine, I did not do any backup processing, other small partners if they encounter, remember to back up the data first.

Then, restart the service

[Email protected] ~]# Systemctl restart Docker

OK, the problem is not big, solved.
