Synchronization Between a Backup Node to a Live Node
39.1.1.2.2. Synchronizing a Backup Node to a Live Node As both live and backup servers share the same journal, they do not need to be synchronized. However until, both live and backup servers are up and running, high-availability can not be provided with a single server. After failover, at first opportunity, stop the backup server (which is active) and restart the live and backup servers. In the next release of HornetQ we will provide functionality to automatically synchronize a new backup server with a running live server without having to temporarily bring the live server down.
