Public bug reported: After upgrading my installation from Folsom to Grizzly I received the below error message when attempting to create a volume using the EC2 API (I did not verify with the Nova API).
I have configured two regions; one each with a cinder endpoint. This works for all other services except for cinder currently. The endpoints are seen to be ambiguous because the cinder client (or nova's use of the client) does not take region into consideration. The client uses a servicetype:servicename:endpointtype tuple to determine whether an endpoint is unique. /var/log/nova/nova-api.log: 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 Traceback (most recent call last): 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 File "/usr/lib/python2.7/dist-packages/nova/api/ec2/__init__.py", line 486, in __call__ 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 result = api_request.invoke(context) 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 File "/usr/lib/python2.7/dist-packages/nova/api/ec2/apirequest.py", li ne 79, in invoke 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 result = method(context, **args) 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 File "/usr/lib/python2.7/dist-packages/nova/api/ec2/cloud.py", line 79 0, in create_volume 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 **create_kwargs) 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 File "/usr/lib/python2.7/dist-packages/nova/volume/cinder.py", line 21 7, in create 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 item = cinderclient(context).volumes.create(size, **kwargs) 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 File "/usr/lib/python2.7/dist-packages/nova/volume/cinder.py", line 65 , in cinderclient 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 endpoint_type=endpoint_type) 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 File "/usr/lib/python2.7/dist-packages/cinderclient/service_catalog.py ", line 75, in url_for 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 endpoints=matching_endpoints) 2013-01-24 22:48:26 23673 TRACE nova.api.ec2 AmbiguousEndpoints: AmbiguousEndpoints: [{u'adminURL': u'http://10.55.58.1:8776/v1/df473f958e4f47949282696966e58f49', u'region': u'lcy01', u'id': u'a60223bd41df4cdf8fb28dcdffe5adad', 'serviceName': u'cinder', u'internalURL': u'http://10.55.58.1:8776/v1/df473f958e4f47949282696966e58f49', u'publicURL': u'https://cinder-lcy01.internal/v1/df473f958e4f47949282696966e58f49'}, {u'adminURL': u'http://10.55.62.1:8776/v1/df473f958e4f47949282696966e58f49', u'region': u'lcy02', u'id': u'14de3dace2284d4eaf95576ae7e2e40d', 'serviceName': u'cinder', u'internalURL': u'http://10.55.62.1:8776/v1/df473f958e4f47949282696966e58f49', u'publicURL': u'https://cinder-lcy02.internal/v1/df473f958e4f47949282696966e58f49'}] The endpoints prettyprinted: [ {'adminURL': 'http://10.55.58.1:8776/v1/df473f958e4f47949282696966e58f49', 'region': 'lcy01', 'id': 'a60223bd41df4cdf8fb28dcdffe5adad', 'serviceName': 'cinder', 'internalURL': 'http://10.55.58.1:8776/v1/df473f958e4f47949282696966e58f49', 'publicURL': 'https://cinder-lcy01.internal/v1/df473f958e4f47949282696966e58f49'}, {'adminURL': 'http://10.55.62.1:8776/v1/df473f958e4f47949282696966e58f49', 'region': 'lcy02', 'id': '14de3dace2284d4eaf95576ae7e2e40d', 'serviceName': 'cinder', 'internalURL': 'http://10.55.62.1:8776/v1/df473f958e4f47949282696966e58f49', 'publicURL': 'https://cinder-lcy02.internal/v1/df473f958e4f47949282696966e58f49'} ] Workaround: 1. I created another service name and service type named 'fakecinder' in keystone. 2. I removed the second region's 'volume' endpoint. 3. I then added the following to the second region's nova.conf: 'cinder_catalog_info=fakecinder:fakecinder:publicURL' 4. Restarted nova-api.
