I am in tight corner learning ceph integration into cinder .
ceph -s
    cluster 5c10c447-8b27-42d2-b056-9366e9b56b31
     health HEALTH_OK

            3473 MB used, 24141 MB / 27614 MB avail

controller nodes has all this configuration has cinder sevices running

openstack-service status cinder
MainPID=1457 Id=openstack-cinder-api.service ActiveState=active
MainPID=1505 Id=openstack-cinder-backup.service ActiveState=active
MainPID=1449 Id=openstack-cinder-scheduler.service ActiveState=active
MainPID=4261 Id=openstack-cinder-volume.service ActiveState=active

But creating a volume after integration spins this error
