Hi, I'd guess a non-200 HTTP response code would be more appropriate indeed but it's just a detail.
A successful replication will change a few things on the slave: - increment of generation value - updated indexVersion value - lastReplication will have a new timestamp You can also check for a replication.properties in your slave's data directory.
