      This value will become the Corosync authentication key. To generate
      a suitable value use:
      .
        sudo corosync-keygen
        sudo cat /etc/corosync/authkey | base64 -w 0

      This configuration element is mandatory and the service will fail on
      install if it is not provided.  The value must be base64 encoded.
  stonith_enabled:
    type: string
    default: 'False'
    description: |
     Enable resource fencing (aka STONITH) for every node in the cluster.
     This requires MAAS credentials be provided and each node's power
     parameters are properly configured in its invenvory.

  monitor_host:
    type: string
    description: |
     One or more IPs, separated by space, that will be used as a saftey check
     for avoiding split brain situations. Nodes in the cluster will ping these
     IPs periodicaly. Node that can not ping monitor_host will not run shared
     resources (VIP, shared disk...).
  monitor_interval:
    type: string
    default: 5s

     Time period between checks of resource health. It consists of a number
     and a time factor, e.g. 5s = 5 seconds. 2m = 2 minutes.

      If True enables IPv6 support. The charm will expect network interfaces
      to be configured with an IPv6 address. If set to False (default) IPv4

      NOTE: these charms do not currently support IPv6 privacy extension. In
      order for this charm to function correctly, the privacy extension must be
      disabled and a non-temporary address must be configured/available on
      your network interface.
