I avoid migrating to a new major version so fast. I usually wait a few years and until than solusions will have been established. I’m currently running a rock-solid dovecot 2.2 cluster and am migrating this to dovecot 2.3 (not 4) now. :D
So wihtin the next couple of years, I’m planing to setup a shared storage (i.ex. GlusterFS) Cluster for underneath.
This will be my current „migration plan“ to dovecot not supporting replication anymore:
2 x Loadblancers (accross two sites) with keepalived and haproxy 3x GlusterFS nodes 3x Galera Cluster mariadb nodes 2x dovecot IMAP with Postfix SMTP (wihout director there’s no need anynmore to use dovecot SMTP implementation)
The Loadbalancer-, Galera- and Gluster modes are shared wit the existing web service infrastructure, so not dedicated to dovecot.
If the HA storage and database clusters will be used dedicated for mail, this makes 11 nodes for a fully HA cluster accross two sites. With virtualization infrastructure that should not get very expensive.

Hei,
mit 2.4 verschwindet ja, wenn ich das richtig verstanden habe, die Replication aus dem Werkzeugkasten von Dovecot. Obwohl ich nur ein recht kleines System mit etwa 500 Nutzern betreibe fand ich die Replication als ziemlich beruhigend :-)
Meine Frage in die Runde: Wie wollt Ihr die Replikation ersetzen? Irgendwas mit NFS oder gibt es da eine empfohlene Herangehensweise?
Fragende Grüße
Hanns
