Ocata release. Fresh install by following the documentation for Ubuntu. I can create volumes and can see them with "lvscan". tgt runs. However when i try to attach a volume to instance or create a volume within instance i get this error on horizon:

1. Error: Failed to perform requested operation on instance xxx, the instance has an error status: Please try again later [Error: Build of instance xxx aborted: Block Device Mapping is Invalid.]. So i've checked the logs and i've found this jewel in compute node1: UnsupportedCinderAPIVersion: Nova does not support Cinder API version 1 see the nova log below:

I've traced and get that cinder v2 started use since Kilo. So why this happens right now? How can we avoid this to hit again?

  1. Admin can create volume with admin account but can't see the volumes on Horizon; I can see volume is there and created both with

    openstack volume list


MariaDB [cinder]> select host, id, user_id, project_id, size, attach_status, status  from volumes;

I believe it is related to this famous API version fun.

Any comments?
