[Csync2] csync2 Master/Slave Setup

[Mohamed King]

Hello Everyone, 

I have a 2 node master/slave setup (only the master can send updates). They are both Web servers that take user uploads and they are in a active/passive mode. I use heartbeat to failover to the standby node. In a situation where the master nodes goes offline and the standby takes over and users upload files while the standby is in active mode. How do I get my master updated when it comes back online? In other other words how do I bypass the restriction I have set in the configuration to prevent the salve from sending updates?
