Description of problem:
One of the necessary parameters in needed to configure the Ceph backend is missing from the hostgroup parameters:
As described in the page http://ceph.com/docs/next/rbd/rbd-openstack/ the cinder needs to use the cinder client keyring file, located in /etc/ceph/ .
Version-Release number of selected component (if applicable):
There's a parameter for ceph password
At the current time, ceph is not configured through RHEL-OSP Installer. The configuration is done externally. A future feature exists that will add this functionality, but for now, this is notabug
