Re: Replication: Can't unsubscribe from shared mailbox

16 Jan 2017


      Hi all,
I hope it's okay to bump this once after four months.
In the meantime we updated to 2.2.26.0 and our problem still persists:
After unsubscribing from a shared mailbox, the subscription instantly re-appears.
A pcap was attached to my original mail, in case it has something to do with dsync:
http://dovecot.org/pipermail/dovecot/2016-September/105419.html
Is anyone on this mailing list using replication in combination with shared folders?
Does this problem exist for anyone else? I would love to hear from people who got this working or if anyone else is affected by this.
My original post is at the end of this email; the current doveconf is also attached.
Thank you very much,
Karsten

Hi,
I am running two dovecot servers active/active.
Everything runs pretty great, except for the replication of subscriptions in a shared namespace.
When I unsubscribe from a folder the subscription instantly re-appears. The timestamp on the subscriptions file is updated, but the entry is still in there.
If the other node is shut down, everything works as expected, which leads me to believe that the subscription is re-applied upon a replicator-run.
I attached a tcpdump of a dsync run.
The only action that was executed was to unsubscribe from the folder shared/weinrot@luis.uni-hannover.de/INBOX.
Is there any other way I might help debugging this?
Thanks,
Karsten
