After CAA services start successfully, the  PowerHA_NFS_Reserve  file is cleaned up for the next  cluster split event. Example 9-55 shows that the size of PowerHA_NFS_Reserve file is  changed to zero after the CAA service is restored. Example 9-55 NFS file zeroed out after the CAA is restored 9.9.6 Scenario summary When the NFS tiebreaker is set as a split and merge policy when a cluster split occurs, the  TBGL has a higher priority to reserve NFS. Other nodes restart, and the RGs are online on  the surviving node. During the cluster merge process, the NFS tiebreaker reservations are released  automatically. Chapter 9.
