dsync FAQ

Note: There currently aren't a lot of frequently asked questions on dsync, but in preparation of publishing the new multiserver guide, I want to be one step ahead.
Some commands that are good to know:
To view the status of replication:

Code:

doveadm replicator status

To show the users that are replicated:

Code:

doveadm replicator status '*'

Do a manual sync:

Code:

doveadm sync -A tcp:mx1.example.com

Initiate a replication of one mailbox manually:

Code:

doveadm sync -u [email protected] tcp:mx1.example.com

If your system is not syncing, make sure:
- The correct settings (noted in the perfect multiserver guide) for Dovecot are placed in /etc/dovecot/conf.d/99-ispconfig-custom-config.conf and in /usr/local/ispconfig/server/conf-custom/install/dovecot_custom.conf.master.
- Both servers have a valid SSL certificate for the hostname.
- The doveadm_password (set in the earlier mentioned config file) is the same on both servers.
- The servers can reach each other and the doveadm_port is opened in the firewall of both servers (but only for traffic from each other - don't open this port publicly).
