[Dovecot] Dsync didn't updates automatically
Hi,
I'm trying to use the Dsync cluster feature in a simple setup, without director, but I'm having some troubles.
First of all, I want to know if this functionality syncs the mailbox when the user receive a mail or only when the dovecot starts?
Reading the Dovecot mailing list and the design description for a dsync-replicated Dovecot cluster, I understood that it should sync every time a new mail arrives, but it isn't happening in my system. So, can I do this update automatically? If yes, why is it not working properly? Maybe is my configuration files or maybe I'm confusing the capability of this feature.
I'm using Dovecot 2.1.7 included in the Debian Wheezy, with virtual users in a MySQL database, Moreover, I have the following configuration:
mail_plugins = $mail_plugins notify replication
service aggregator {
give enough permissions for mail processes
fifo_listener replication-notify-fifo { user = vmail #mode = 0666 } unix_listener replication-notify { user = vmail #mode = 0666 } }
service replicator {
start replication at startup
process_min_avail = 1 }
plugin {
host1 replicates to host2
#mail_replica = remote:vmail at 10.127.0.2
host2 replicates to host1
mail_replica = remote:vmail@10.127.0.5 }
dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace}
service doveadm {
if you're using a single virtual user, set this to
start ssh as vmail (not root)
user = vmail }
service config { unix_listener config { user = vmail } }
The vmail user has rsa id's in both servers, so it can do ssh connections without asking for password.
I appreciate your help. Best Regards,

Both, if configured correctly.

Does it sync at startup either? Anything in error log? http://wiki2.dovecot.org/Replication also describes the configuration.

Hi Timo, Thanks for your answer.
Good to know that it can sync when a new mail arrives.
I've already seen this wiki page, my configuration is almost the same that the one described there. It syncs at startup, but doesn't syncs when a new email arrives, and that is my problem.
In error log, some messages are printed when Dovecot starts:
Jan 4 13:22:21 srv1 dovecot: master: Dovecot v2.1.7 starting up (core dumps disabled) Jan 4 13:22:21 srv1 dovecot: auth-worker(4322): mysql( supra-lb.testesupra.com.br): Connected to database Supramail Jan 4 13:22:21 srv1 dovecot: doveadm(nobody): Fatal: setgid(65534(nogroup) from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail), egid=5000(vmail): Operation not permitted (This binary should probably be called with process group set to 65534(nogroup) instead of 5000(vmail)) Jan 4 13:22:21 srv1 dovecot: doveadm(mav): Fatal: setgid(1000(mav) from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail), egid=5000(vmail): Operation not permitted (This binary should probably be called with process group set to 1000(mav) instead of 5000(vmail))
But when there is a new mail, it only prints a success message:

Timo,
It did the trick and solved my problem. Thanks for your help.
I have just one more question: In Dovecot 2.1.7, it will make a full sync every time a new mail arrives or it can make the fast sync?
