Cluster Administration

Click the Magnify icon to view the NAS Administrator.

To properly configure a cluster using NAS Administrator, all the servers in the cluster must be registered. Otherwise, configuration changes are not applied across all the servers in the cluster.

The NAS Administrator can perform the following tasks to configure clusters:

  • Add a server to a cluster
  • Remove a server from a cluster
  • Change a server's Sync Server priority
  • Modify the maximum number of Sync Backups

  1. From the NAS Administrator toolbar, click the General button to open the General window.
  2. In the right pane of the General window, click the Cluster tab.
  3. Double-click inside the Cluster Name drop-down box to select hostname-No-Dsync.
  4. Use the Delete key to clear the Cluster Name drop-down box.
  5. Type the name of the new cluster in the Cluster Name drop-down box and press Enter. Choose any unique name for the new cluster.
  6. Click Apply Changes.
