1) Stop docker: service docker stop. Verify no docker process is running ps faux
2) Double check docker really isn't running. Take a look at the current docker directory: ls /var/lib/docker/
2b) Make a backup - tar -zcC /var/lib docker > /mnt/pd0/var_lib_docker-backup-$(date +%s).tar.gz
3) Move the /var/lib/docker directory to your new partition: mv /var/lib/docker /mnt/pd0/docker
4) Make a symlink: ln -s /mnt/pd0/docker /var/lib/docker
5) Take a peek at the directory structure to make sure it looks like it did before the mv: ls /var/lib/docker/ (note the trailing slash to resolve the symlink)
6) Start docker back up service docker start
