处理方法如下：

docker中默认存放镜像和容器的目录是：/var/lib/docker/，将/var/lib/docker/给删除并重启服务，解决了docker无法正常启动的问题。

rm -rf /var/lib/docker/
vim /etc/docker/daemon.json
{
     
    "graph": "/mnt/docker-data",
    "storage-driver": "overlay"
}

再重新启动服务，docker服务已经正常

systemctl restart docker
systemctl status docker

服务器重启docker报错2
