Add Medium Gear Capablity on OpenShift

The OpenShift Virtual Machine download is pre-configured with one node, in one district with a small gear profile. There are two ways to add another gear size

• add another node, in a new district with medium gears, but easier is it to
• remove the district restriction and allow both small and medium gears.

Edit the /etc/openshift/plugins.d/openshift-origin-msg-broker-mcollective.conf, and set
DISTRICTS_ENABLED=false
DISTRICTS_REQUIRE_FOR_APP_CREATE=false
NODE_PROFILE_ENABLED=false
ZONES_REQUIRE_FOR_APP_CREATE=false

Next in edit the /etc/openshift/broker.conf and set
VALID_GEAR_SIZES="small,medium"
DEFAULT_GEAR_CAPABILITIES="small,medium"

Then restart the node to let the changed take effect. If you have an existing user you may need to add the medium capability explicitly  using something like oo-admin-ctl-user -l demo --addgearsize medium.
