We have two openldap 2.4.7 , configured as MirrorMode, We are planning to add load balancer in front of both servers into the production environment, We don't want too go through conflicts issues as it was stated before as messy process.
--------- --------- . . . . . Srv1 . . Srv2 . --------- --------- \ / ---- ------------ . LoadB . .-------.
As per my understanding, the load balancer(failover mode) is redirecting all traffic to the active server(srv1); if the active server went down the traffic will be redirected to stand-by server(srv2). When srv1 goes online again the load balancer will redirect all trafic to srv1, while srv1 is in progress to get synced with srv2. The load balancer will not consider the sync process; it will just redirect the traffic.
it was previously stated on the mailing list that there should be one write at a time. is there any conflict will occur when server getting bulk syncing and receiving updates(attribute level)/add requests as well?
What happen if there attribute-level conflict? how to avoid it? suggestions are highly welcomed.
