Hi, I was wondering what people consider best practice as failover scenario in a replication enviroment. Right now, it looks tricky to me to enable replication after failover, or the replicated machine itself if you're not sure that the replica is identical and the sync-processes finished completely: if a message-file is in place on machine A (say "7.") but it was not replicated to machine B while that one becomes the master, the machine B will create a new file 7. and both machines consider this file synchronised after that: also if roles switch back, you have two different (with one isolated) copies of 7. (Probably a thorough check is needed to ensure the consistency 'once again' and copy files from one side to the other... so I hope that's where best practice comes in ;-)) Or is it only preferred to use a replica if there is a really serious crash on the (previous) master? It sounds nice to me if I could use heartbeat or (u)carp (/ifstated) like systems to start and stop a sync_client or sync_server copy of cyrus (both different cyrus.conf) as soon as the state of the virtual interface changes, but then it is even more likely that some replication process is not finished without an admin even noticing it.
