I have observed my mail storage directories on both instances and have noticed that they diverge a little over time - the instance B not having all the updates. However the moment I connect another client to instance B and log in as a particular user, the state on instance B springs to the correct state and I see the same content on both clients, and the storage directories become identical as well.
Are there any replication errors logged? Does doveadm replicator status or doveadm replicator status <mailbox> give any sign of errors?
Can you give some example or evidence of the disalignment that is happening?
Thank you for response. I was asking if such difference in directories is normal or not and do I have the approach right or is there some obvious error in my configuration.
I still have an example that prompted me to write this email. Instance B had three mails missing in comparison to instance A, when I listed the storage directories from the command line. They got replicated fine just after I connected a client to instance B. No difference since then, but I need to observe the servers for some more time, it seems like it happens over a few weeks or so. No errors in dovecot logs, doveadm replicator status output does not show any errors as well, but instances have been restarted, so it is not a goof indication. I am going to enable debug to see what's going on. Maybe it was some transient situation or human error on my part during setting it all up or tweaking the configuration. I will come back if I observe such thing again.
Here are the listings. Hostnames etc. replaced for privacy.
