    type: string
  EndpointMap:
    default: {}
    description: Mapping of service endpoint -> protocol. Typically set
                 via parameter_defaults in the resource registry.
    type: json
  ServiceData:
    default: {}
    description: Dictionary packing service data
    type: json
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry. Use
                 parameter_merge_strategies to merge it with the defaults.

  LVMFilterEnabled:
    default: false
    description: Enables configuration of LVM2 with a filter so that devices not
                 in use on the host or explicitly allowed are ignored by
                 LVM2. Can be configured per-role.
                 When disabled, the proposed lvm.conf file will be created
                 regardless and left in /tmp/tripleo_lvmfilter.conf for
                 debugging purposes.

                 time will be automatically allowed.

  LVMFilterDenylist:

    description: A list of block devices which should be disallowed in the LVM2
