Openstack Cinder Block Storage
==============================

Cinder provides an infrastructure for managing volumes in OpenStack. It was
originally a Nova component called nova-volume, but has become an independent
project since the Folsom release.

Sample pillars
==============

New structure divides cinder-api,cinder-scheduler to role controller and
cinder-volume to role volume.

          members:

Client-side RabbitMQ HA setup for volume component

.. code-block:: yaml

          engine: rabbitmq
          members:

**Client-side RabbitMQ TLS configuration.**

|

To enable TLS for oslo.messaging you need to provide the CA certificate.
By default system-wide CA certs are used. Nothing should be specified except `ssl.enabled`.

.. code-block:: yaml

  cinder:
    controller or volume:
      ....
      message_queue:
        ssl:
          enabled: True


Use `cacert_file` option to specify the CA-cert file path explicitly:

.. code-block:: yaml

  cinder:
    controller or volume:
      ....
      message_queue:
        ssl:
          enabled: True
          cacert_file: /etc/ssl/rabbitmq-ca.pem

To manage content of the `cacert_file` use the `cacert` option:

.. code-block:: yaml

  cinder:
    controller or volume:
      ....
      message_queue:
        ssl:
          enabled: True
          cacert: |

          -----BEGIN CERTIFICATE-----
                    ...
          -----END CERTIFICATE-------

          cacert_file: /etc/openstack/rabbitmq-ca.pem


Notice:
 * The `message_queue.port` is set to **5671** (AMQPS) by default if `ssl.enabled=True`.
 * Use `message_queue.ssl.version` if you need to specify protocol version. By default is TLSv1 for python < 2.7.9 and TLSv1_2 for version above.

public_endpoint and osapi_volume_base_url parameters:
"public_endpoint" is used for configuring versions endpoint,
"osapi_volume_base_URL" is used to present Cinder URL to users.
They are useful when running Cinder under load balancer in SSL.

.. code-block:: yaml

    cinder:
      controller:
        public_endpoint_address: https://${_param:cluster_domain}:8776

The default availability zone is used when a volume has been created, without specifying a zone in the create request. (this zone must exist in your configuration obviously)
The storage availability zone is the actual zone where the node belongs to. Make sure to specify this per node.
Check the documentation of OpenStack for more information

Documentation and Bugs
============================

To learn how to deploy OpenStack Salt, consult the documentation available
online at:

https://wiki.openstack.org/wiki/OpenStackSalt

In the unfortunate event that bugs are discovered, they should be reported to
the appropriate bug tracker. If you obtained the software from a 3rd party
operating system vendor, it is often wise to use their own bug tracker for
reporting problems. In all other cases use the master OpenStack bug tracker,
available at:

    http://bugs.launchpad.net/openstack-salt

Developers wishing to work on the OpenStack Salt project should always base
their work on the latest formulas code, available from the master GIT
repository at:
