OpenShift v3 setup - WORK IN PROGRESS

Skip if you're not using Atomic.

If using Fedora/Centos/RHEL Atomic, make sure you've either added a second disk big enough for your Docker images/containers. If you've added a second disk, then you should edit /etc/sysconfig/docker-storag-setup & add in the following:

DEVS=/dev/vdb

Then run sudo docker-storage-setup & your new disk will be used for docker storage.
