docker dm_task_run failed 启动失败解决办法

Error response from daemon: Error running DeviceCreate (createSnapDevice) dm_task_run failed

故障说明：删除容器的时候选择了自动删除卷

原因：devicemapper的metadata异常

# systemctl stop docker.service
# thin_check /var/lib/docker/devicemapper/devicemapper/metadata
           

# thin_check --clear-needs-check-flag /var/lib/docker/devicemapper/devicemapper/metadata
# systemctl start docker.service
