CONFIGURING CINDER
OpenStack requires a driver to interact with Ceph block devices. You must also specify the pool name for the block device. On your OpenStack node, edit/etc/cinder/cinder.conf by adding:
[DEFAULT] ... enabled_backends = ceph ... [ceph] volume_driver = cinder.volume.drivers.rbd.RBDDriver rbd_pool = volumes rbd_ceph_conf = /etc/ceph/ceph.conf rbd_flatten_volume_from_snapshot = false rbd_max_clone_depth = 5 rbd_store_chunk_size = 4 rados_connect_timeout = -1 glance_api_version = 2
systemctl status openstack-cinder-volume.service

Hi Gaurav,
Unfortunately I'm not completely sure about your setup, but I guess it
makes sense to configure Cinder and Glance to use RBD for a backend. It
seems to me, you're trying to store VM images directly on an OSD filesystem.
Please refer to http://docs.ceph.com/docs/master/rbd/rbd-openstack/ for
details.
Regards,
Kees
