rhel-osp-director: Unable to launch nova instances with ceph storage, that wasn't installed with the overcloud deployment. The overcloud deployment connected to an existing ceph storage. Environment: openstack-tripleo-heat-templates-0.8.6-62.el7ost.noarch instack-undercloud-2.1.2-26.el7ost.noarch Steps to reproduce: 1. Deploy an overcloud with existing external ceph storage. Here's the deployment command: openstack overcloud deploy --templates --control-scale 3 --compute-scale 1 --ceph-storage-scale 0 -e <yaml> -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-ceph-external.yaml --ntp-server x.x.x.x --timeout 90 --compute-flavor compute --control-flavor control 2. Connect to the overcloud, create networks, download glance image and attempt to boot the instance. Result: The instance gets status: ERROR Expected result: The instance should be boot successfully. Note: I was able to create the glance and cinder images on the external ceph storage.
