Fencing resources are not configured even though FencingConfig in fencing.yaml is written

Issue

• FencingConfig is written in fencing.yaml file.

  parameter_defaults:
    EnableFencing: true
    FencingConfig:
      devices:
        - agent: fence_ipmilan
          host_mac: 00:00:00:00:00:aa
          params:
            ipaddr: 10.0.0.1
            lanplus: true
            login: admin
            passwd: ****
            pcmk_host_list: overcloud-controller-0
        - agent: fence_ipmilan
          host_mac: 00:00:00:00:00:bb
          params:
            ipaddr: 10.0.0.2
            lanplus: true
            login: admin
            passwd: ****
            pcmk_host_list: overcloud-controller-1
        - agent: fence_ipmilan
          host_mac: 00:00:00:00:00:cc
          params:
            ipaddr: 10.0.0.3
            lanplus: true
            login: admin
            passwd: ****
            pcmk_host_list: overcloud-controller-2
  

• The aforementioned fencing.yaml is included in openstack overcloud deploy command.

  $ openstack overcloud deploy \
         :
    -e /home/stack/templates/fencing.yaml \
         :
  

• However, no fencing resources are configured in the overcloud Pacemaker cluster.

  # pcs config
    :
  Stonith Devices:
  Fencing Levels:
    :
  
    ===> "Stonith Devices" and "Fencing Levels" are empty.
