Hi,
I've setup a multimaster cluster composed of two machine (in my example 192.168.0.204 and 192.168.0.197). Everything is working ok and both side are replicating ok.
However, I've a problem I'd like to submit to your sagacity.
When I put down a server, and modify the other server (delete or add), when the first server comes back, the modifications are not pushed in the old server. Server 1 says Entry cn=seb,ou=orgunit,o=org,dc=example,dc=com changed by peer, ignored
Adding new entries works ok and synchronisation happens but for the nodes altered while one of the servers was down, the modifications are lost (or more precisely ignored by the other).
My questions: Is this normal behaviour (Maybe I got the configuration wrong) ? How may I force the missing entries to be replicated to the other ? (Only solution I found is to wipe the entire database on the down server that force a replication from its peer).
sincerely, Seb
