We are having 3 openldap 2.4.33 servers on rhel 6.3 in MMR, below is my
replication status for all of them.
We have imported all the data on one server and copied same data to other
#000# is the CSN created before MMR was set up, so there were no servers with any server ID, i.e., one server with a server ID of zero. This context CSN will never update.
#001# is the CSN of the server with ServerID 1.
#002# is the CSN of the server with ServerID 2.
#003# is the CSN of the server with ServerID 3.
The 001 through 003 CSNs will reflect the last time any of those servers had a direct *not replicated* update. For testing if a server is up to date, you want to compare all the CSNs to one another between the two servers.
I.e., you want CSN 001 to match CSN 001 on both servers. CSN 002 to match CSN 002 on both servers. CSN 003 to CSN 003 on both servers. I wrote a rather fun perl script for Zimbra to do this across a MMR setup.
I will note that delta-syncrepl MMR remains the best option for configuring MMR, as it is the least likely to end up with conflicts, unless you run purely in MirrorMode. It also retains the bandwidth and write throughput advantages it has with provider/replica replication as well.
