Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/cinder" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Modify API to include cluster related operations

    This patch adds new API /cluster that allows summary and detailed
    listings, show and update operations.

    It also updates service listings to return cluster_name for each
    service.

    DocImpact: 3 new policies have been added for cluster, "get", "get_all" and
               "update".
    APIImpact: Return cluster_name in service listings and add /cluster endpoint.

This was fixed in openstack-manuals. Don't need it open in Cinder.
