I cant start docker.service after using systemctl restart docker.service. Before doing this, the docker service works well on my servers.

I tried to add { "storage-driver": "devicemapper" } to the /etc/docker/daemon.json. The docker service can be started. But the docker images and the containers are all missing.

    sh$ df -h
    [docker]# df -h
    Filesystem      Size  Used Avail Use% Mounted on
    /dev/vda1        50G   18G   30G  38% /
    devtmpfs        1.9G     0  1.9G   0% /dev
    tmpfs           1.9G   24K  1.9G   1% /dev/shm
    tmpfs           1.9G  356K  1.9G   1% /run
    tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
    tmpfs           380M     0  380M   0% /run/user/0
    tmpfs           380M     0  380M   0% /run/user/1000

On the other hand, when I remove { "storage-driver": "devicemapper" } from /etc/docker/daemon.json. And then I do mv /var/lib/docker /var/lib/docker_cp. The docker service can also be started. But all the docker images and containers are missing.

So how to start the docker service with exists images and containers?
