Andreas Jaeger 99ec31f53f Docs: Make links more robust 
Some docs used external links which cannot be verified and thus we
easily might get broken links. Use internal links that Sphinx can verify.

Some additional updates:
* Update tox.ini to not publish the dirtrees.
* Update openstack mailing list to openstack-discuss
* Remove reference to not anymore existing 'OpenStack Configuration
  Reference'

Manage Block Storage service quotas

As an administrative user, you can update the OpenStack Block Storage service quotas for a project. You can also update the quota defaults for a new project.

Block Storage quotas

Property name Defines the number of

gigabytes

Volume gigabytes allowed for each project.

snapshots

Volume snapshots allowed for each project.

volumes

Volumes allowed for each project.

View Block Storage quotas

Administrative users can view Block Storage service quotas.

  1. Obtain the project ID:

    $ PROJECT_ID=$(openstack project show -f value -c id PROJECT_NAME)

  2. List the default quotas for a project:

    $ openstack quota show --default $PROJECT_ID

Note

Listing default quotas with the OpenStack command line client will provide all quotas for storage and network services. Previously, the cinder quota-defaults command would list only storage quotas. You can use $PROJECT_ID or $PROJECT_NAME arguments to show Block Storage service quotas. If the $PROJECT_ID argument returns errors in locating resources, use $PROJECT_NAME.

  1. View Block Storage service quotas for a project:

    $ openstack quota show $PROJECT_ID

Edit and update Block Storage service quotas

Administrative users can edit and update Block Storage service quotas.

  1. To update a default value for a new project, update the property in the cinder.quota section of the /etc/cinder/cinder.conf file. For more information, see the Block Storage service configuration </configuration/index>.

  2. To update Block Storage service quotas for an existing project

    $ openstack quota set --QUOTA_NAME QUOTA_VALUE PROJECT_ID

    Replace QUOTA_NAME with the quota that is to be updated, QUOTA_VALUE with the required new value. Use the openstack quota show command with PROJECT_ID, which is the required project ID.

    For example:

    $ openstack quota set --volumes 15 $PROJECT_ID
$ openstack quota show $PROJECT_ID
