Keep these tips in mind when installing FSE on a CCR cluster:

  • Never configure FSE by connecting directly to the passive node of a CCR cluster.

  • The Quarantine and Incident databases are not replicated. To release an item from quarantine on the passive node, connect directly to the passive node. Do not make any other configuration changes.

  • After saving configuration changes on the active node you must allow time for a replication cycle to complete before failing over to the passive node. The default replication cycle is 30 seconds for configuration files and five minutes for engines.

  • Do not configure FSE on the passive node separately. Configure it on the active node and the replication cycle will copy all your configuration settings.

  • If you need to convert an existing CCR cluster node with FSE to a standalone server, FSE must be uninstalled and reinstalled.

  • The FSE replication service creates backup files on startup and whenever a transition from active node to passive node occurs. These files can be used for recovery if current configuration data is accidentally overwritten with older configuration data.

  • On a CCR cluster system, the Redistribution Server option is automatically selected in the General Options pane. This option is required for successful engine updates on the cluster. Do not disable this option. If this option is disabled, you can select the Redistribution Server check box again to restore engine updates. Each engine will require a new update before it can be replicated correctly again.
