A while back there was some discussion of supporting Master-Master
replication in Cyrus. I'm busy updating from 2.4.17 to 3.0.2. What is
the state of Master-Master, as opposed to Master-Replica replications?
My current configuration is a Murder cluster with three front-end
servers, two back-end servers, each with their own replication server.
One pair of Master-Replica are empty of mailboxes at the moment, prior
to upgrade.
Continuing my question, what I am thinking is:
Create imap.conf files on each server:
Server be1: partition-default /var/spool/imap1
Server be2: partition-default /var/spool/imap2
Create replication.conf files on each server:
Server be1: partition-default /var/spool/imap2
Server be2: partition-default /var/spool/imap1
replication.conf would be used for the syncserver process on each be server.
The idea is that the imap processes know of one set of partitions, and
the replication process knows of the other. Each mupdatepush process
will only inform the Cyrus front-end master of its own master partition.
The IMAP processes will only place it's own partitions in the
synchronization log.
Thoughts?
Mike
