Hi,

just in the process of setting up cinder and cinder-volume on the storage nodes is ignoring the rabbit settings:

/etc/cinder/cinder.conf

[DEFAULT]
rpc_backend = rabbit

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = secretpassword

Error message:

Any idea why its ignoring the settings? Network connectivity is working, rabbitmq is reachable... Running on Ubuntu 14.04 with liberty:

dpkg -l |grep cinder-volume
ii  cinder-volume                        1:2014.1.5-0ubuntu2              all          Cinder storage service - Volume server

UPDATE

When I hack my rabbitmq connection into /usr/lib/python2.7/dist-packages/oslo/messaging/_drivers/impl_rabbit.py its working.

When i am creating a image now, I get following error (not sure if this is related):
