Hello Vikrant

Check permission of your of cinder.conf and glance-api.conf configuration file.

Many Thanks

Hi Steffen,

When i run the command  " rbd --id glance ls images" i am getting following error 

2013-12-27 17:44:56.493670 7fe56c754780  0 librados: client.glance authentication error (1) Operation not permitted

rbd: couldn't connect to the cluster!

and so is the case with cinder. Please let me know where i am wrong

I want to create a Ceph Boot Volume and launch an instance from this volume. I have posted my actual issue at - 

https://answers.launchpad.net/cinder/+question/241336

Please find  my glance-api.conf  as an attachment.

Hi Vikrant,
there is a difference between ceph openstack doc http://ceph.com/docs/master/rbd/rbd-openstack/ and your glance-api.conf (ubuntu) defaults.

rbd_store_ceph_conf = /etc/ceph/ceph.conf

# RADOS user to authenticate as (only applicable if using cephx)

rbd_store_user = glance

# RADOS pool in which images are stored

rbd_store_pool = images

I think you should change only the following line in your glance-api.conf
default_store = rbd


the default name of the rbd pool is images:
ceph osd pool create images 128

the default user is glance:
ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images'

on your glance server side you need then /etc/ceph/ceph.conf and /etc/ceph/ceph.client.glance.keyring

to test the authentication on your glance host:
   rbd --id glance ls images

and now it should work.

Regards,
  Steffen
