Hi,
I have a setup with several dovecot-servers (2.2.35) and I use dovecot proxy. I upgraded one server to 2.3.1 and got the configs fixed so far that it started again. But when I tried to add it into the proxying again with "doveadm director add" I see the following in the logfiles:
May 6 07:19:30 host dovecot: director: Warning: Director xxx.xxx.xxx.176:9090/out disconnected us with reason: Invalid input: OPTIONS May 6 07:19:30 $host dovecot: director: Connecting to xxx.xxx.xxx.171:9090 (as xxx.xxx.xxx.176): Reconnecting after error
xxx.xxx.xxx.176 is the upgraded host, xxx.xxx.xxx.171 is one of the other hosts (the applicable hosts are in the range xxx.xxx.xxx.171-176).
Do I have to remove all the hosts from the proxy, upgrade them and then add them again? Or is there a way to handle the upgrade without a downtime? After all one of the reasons I use several hosts is that I do not want to have a downtime.
