OpenStack Juno : Configure Cinder#1 ( Control Node )2015/01/11
 
Install and Configure OpenStack Block Storage (Cinder).
For this example, Install Cinder API Server on Control Node which Keystone/Glance/Nova API are already installed, and Install Cinder-Volume on Block Storage Service Node. ( it's possible to install on a server as All-in-One, though, if you want )
