There are duplicate Availability Zone "nova".

[TsutomuNakamura]

After running this Ansible, we will see duplicate zones "nova".

dev-controller01 # openstack availability zone list
+-----------+-------------+

| internal  | available   |
| nova      | available   |

There are instructions to add zone nova duplicated in import_playbook: cinders.yml. https://github.com/tsuna-server/build-server-ansible/blob/3615fe0a5f3624bca776b0fcc790dfe30dd8364e/site.yml#L1-L10

[TsutomuNakamura]

The conditionals registering duplicate Nova region are ...

• Nova role in any group (Controllers?)

• Configure /etc/cinder/cinder.conf on controller nodes. https://github.com/tsuna-server/build-server-ansible/blob/3615fe0a5f3624bca776b0fcc790dfe30dd8364e/roles/cinder/tasks/set_configuration/cinders/main.yml#L15-L24

Either notify tgt or cinder-volume are not a cause of registering nova region. Just modifying /etc/cinder/cinder.conf cause registering nova region. (?)

[TsutomuNakamura]

nova region will be registered when the cinder-volume daemon was restarted.

Duplicate availability zones are computes and volumes.
