## 9.9.5 Cluster merge 

The steps are similar to 9.8.5, “Cluster merge” on page 375. 

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.

## 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.
