Abstract
In a distributed replicated storage system, an active server may, during normal operation, service requests from clients, and back up its persistent storage to a backup server. The backup server may be configured to become an active server autonomously if the active server fails. If a network connection between the active server and the backup server fails, severing the connection between the active server and the backup server, the backup server may become a second active server and begin to service requests from clients, and the original active server may continue to service requests from clients. This may result in inconsistencies in the persistent storage of the original active server and of the second active server. As such, a system and method for intelligent merging of primary and backup data in a distributed replicated storage system are provided.
