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 = -1glance_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 parameters
      should 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-volumes

        Do i need to execute following commands? 
        "pvcreate /dev/rbd1" &
"vgcreate cinder-volumes /dev/rbd1"
