Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/nova" 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.

commit ad6654eaa7c44267ae3a4952a8359459fbec4c0c
Author: Sylvain Bauza <sbauza@xxxxxxxxxx>

    Update ComputeNode values with disk allocation ratios in the RT
    
    Now that we have added the field for persisting the disk alloc ratio, we can
    have the ResouceTracker persisting it by adding it to the local ComputeNode
    object which is persisted by calling the _update() method.
    It will then send by default 0.0 unless the operator explicitely specified an
    allocation ratio in the compute nova.conf.
    
    Thanks to the ComputeNode object hydratation on the scheduler side, the facade
    will make sure that if a default 0.0 is provided by either a compute node or
    by the scheduler's nova.conf, it will actually get the original allocation
    ratios (ie. 1.0 for disk)
    Since the Scheduler reads the same RT opt but goes thru the ComputeNode object,
    it will also get the Facade returning 1.0 unless the operator
    explicitely provided other ratios for the scheduler's nova.conf
    
    Amending the release note now that the behaviour is changing.
    
    DocImpact Disk alloc ratio is now per computenode
