I’ve installed docker on fedora 21. I wanted to change docker image locations from default /var/lib/docker. After copying files (devicemapper subfolder skipped, docker service stopped) and changing /etc/sysconfig/docker (adding -g option), I run docker service again, no problems, devicemapper/metadata created.
Next, I'm trying to pull first image:
docker pull centos
But this error occurred:
docker pull centos
latest: Pulling from docker.io/centos

It works completely fine if I run this command without changing the locations of images.
