Determine if the WildFire Cluster is in a Split-Brain Condition

When the appliances in a WildFire 2-node cluster enter a split-brain condition, the service failure(s) generate warnings in the WildFire CLI and managing Panorama (where available).
  1. (WildFire appliance CLI only) On a WildFire appliance controller, run:
    admin@WF-500>
    show cluster membership
    The affected WildFire cluster node displays
    Cluster:splitbrain
    next to
    Service Summary
    .
    The following example shows a node in a 2-node WildFire cluster in a split-brain condition:
    Service Summary: Cluster:splitbrain Cluster name: WF_Cluster_1 Address: 2.2.2.114 Host name: wf1 Node name: wfpc-009707000380-internal Serial number: 009707000380 Node mode: controller Server role: True HA priority: secondary Last changed: Tue, 24 Oct 2017 15:13:18 -0700 Services: wfcore signature wfpc infra Monitor status: Serf Health Status: passing Agent alive and reachable Service 'infra' check: passing Application status: global-db-service: ReadyLeader wildfire-apps-service: Ready global-queue-service: ReadyLeader wildfire-management-service: Done siggen-db: ReadyMaster Work queue status: sample anaysis queued: 0 sample anaysis running: 0 sample copy queued: 0 sample copy running: 0 Diag report: 2.2.2.114: reported leader '2.2.2.114', age 0. 2.2.2.114: local node passed sanity check.
  2. (Panorama only) On the Panorama appliance that is managing the WildFire cluster:
    1. Select
      Panorama > Managed WildFire Clusters
      .
    2. In the
      Cluster Status
      column, check for the presence of
      cluster [splitbrain]
      . This indicates that the appliance is in split-brain mode.
