Bug Description

cinder endpoint v2 changed the volume names attr to --name instead of --display-name.

when I change the cinder endpoint to v2 and create volumes, horizon crashes when we try to query the volumes:

AttributeError: display_name

to reproduce:
Run the following in cli:

1. install openstack with packstack
2. change cinder's endpoint in keystone to v2:

keystone endpoint-create --region RegionOne --service-id 10fd33fdca4f4ca4a2e21c2c786a3495 --publicurl 'http://<ip>:8776/v2/%(tenant_id)s' --adminurl 'http://<ip>:8776/v2/%(tenant_id)s' --internalurl 'http://<ip>:8776/v2/%(tenant_id)s'

delete the old v1 endpoint:

keystone endpoint-delete <endpoint that uses v1>

3. create a volume using v2 API:

OS_VOLUME_API_VERSION=2 cinder create 10 --name <name>

4. log in to horizon -> project -> volumes

Horizon gives an attr error on name

I am experiencing this same issue. Whenever I try to access the Volumes tab in Horizon I get the same error message as above.

Cinder Version: 1.0.7

I've also been experiencing this exact same problem with attaching volumes to virtual instances. When I try to attach a volume with the following command:
root@ts036953:/home/pssuser# nova volume-attach fedora1 08d565c2-e5ee-4ca1-8deb-27235396751f /dev/vdb
ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-008288f6-039c-4052-960f-521838515ac0)

And then when I try to attach to device that the instance already has I get the following message. Which kind of indicates that the instance is a least getting touched by the "nova volume-attach" command. What logs can I look into to see more detailed messages on what could be going wrong during this volume-attach attempt?
