报错信息:

devmapper: Thin Pool has 82984 free data blocks which is less than minimum required 163840 free data blocks. Create more free space in thin pool or use dm.min_free_space option to change behavior

解决

Cleanup exited processes:

docker rm $(docker ps -q -f status=exited)

Cleanup dangling volumes:

docker volume rm $(docker volume ls -qf dangling=true)

Cleanup dangling images:

docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

msg=”[graphdriver] prior storage driver overlay2 failed: driver not supported

可能是因为docker版本变化，导致出现该问题

可以尝试

…. code-block:: shell

mv /var/lib/docker /var/lib/docker.old 再启动
