Hello,
You only need a create a pool and authentication in Ceph for cinder.
Your configuration should be like this (This is an example configuration with Ceph Jewel and Openstack Mitaka):
[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
rbd_user = cinder
rbd_secret_uuid = c35bd3d8-ec12-2052-9672d-334824635616
And then, remove the cinder database, recreate and poblate with "cinder-manage db sync". Finally restart the cinder services and everything should work fine.
Regards,
Fran.

Hi Gaurav,
The following snippets should suffice (for Cinder, at least):
[DEFAULT]
enabled_backends=rbd
[rbd]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
rbd_pool = cinder-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
rbd_user = cinder
rbd_secret = REDACTED
backup_driver = cinder.backup.drivers.ceph
backup_ceph_conf = /etc/ceph/ceph.conf
backup_ceph_user = cinder-backup
backup_ceph_chunk_size = 134217728
backup_ceph_pool = backups
backup_ceph_stripe_unit = 0
backup_ceph_stripe_count = 0
restore_discard_excess_bytes = true
Obviously you'd alter the directives according to your configuration and/or wishes.
And no, creating RBD volumes by hand is not needed. Cinder will do this for you.

Yeah i didnt find additional section for [ceph] in my cinder.conf file. Should i create that manually?As i didnt find [ceph] section so i modified same parameters in [DEFAULT] section.I will change that as per your suggestion.
Moreoevr checking some other links i got to know that, i must configure following additional parametersshould i do that and install tgtadm package?rootwrap_config = /etc/cinder/rootwrap.conf api_paste_confg = /etc/cinder/api-paste.ini iscsi_helper = tgtadm volume_name_template = volume-%s volume_group = cinder-volumesDo i need to execute following commands?"pvcreate /dev/rbd1" & "vgcreate cinder-volumes /dev/rbd1"
