The code doesn't allow it so I'm rather baffled as to how you achieved it. Upon initiating each replication transfer, the source server inspects the replica update vector supplied by the destination server. In the case of a newly installed server, that ruv will have a special null value. Receipt of that value causes the source server to refuse to send updates. It prints an error message in the log and basically sulks forever with respect to that replica. At least that's how the code is written and that's how it's always behaved in my experience. You might tell us more about exactly how you are 'dropping and rebuilding' the replica -- possibly you are doing something strange that results in an inconsistency between the server's content and its ruv. Replica initialization is covered in the docs, here : <a class="moz-txt-link-freetext" href="http://www.redhat.com/docs/manuals/dir-server/ag/7.1/replicat.html#1104247">http://www.redhat.com/docs/manuals/dir-server/ag/7.1/replicat.html#1104247</a> Geoff wrote: <blockquote cite="mid:46B25903.3040300@gmail.com" type="cite"> <meta http-equiv="Context-Type" content="text/html; charset=ISO-8859-1"> Correct guys, I did ask how to add a new master and I understand that you would destroy the existing replication agreements to insert the new master. My test involved setting up 4 way (circular) replication agreements between 4 DS. I destroyed one ant the other 3 DS continued to replicate without issue. I then rebuilt and added the 4 DS back in to the 4 way (circular) replication. It did not rebuild itself to contain all of the information the other 3 DS carried and this is what concerned me. When I added a record to any of the masters it would replicate around to all 4DS. But the dropped and rebuilt master never recovered all the data, just added the new additions. I notice you mention "initialize the replica". It sounds like a step I am missing. How does one do that?
