Hi,

I'm trying to get replication to work with a 2 machines setup.

So far full replication is happening at the specified interval (24hrs) without problem but fast sync is not happening. The fast sync counter is always equal to full sync unless i exec dsync manually.

doveadm replicator status '*' username priority fast sync full sync success sync failed johndoe@oricom.dmz none     00:06:33  00:06:33  00:21:33     - johndoe2@oricom.dmz none     00:06:34  00:06:34  00:06:34     - johndoe3@oricom.dmz none     00:06:34  00:06:34  00:06:34     -

The fast replication part is not clear and i cannot find much about it. There is nothing related with dovecot -a and the documentation does not say much about it.

How the fast replication is triggered? Manually or it is supposed to be automatic through some type of config.

Some light over this would help me understand the way it work and how to get it setup right.

yves Fast replication should occur when there are some mails being saved.

Hi, That where is my problem. The fast sync is not triggering and i cannot find any hint of what is wrong. I moved that setup to a production server with a thousand active mailboxes and i get the same result. The only way to get the fast sync to work is calling dsync directly : doveadm sync -d -N -l 30 -U -u '*' Maybe it is in my config.

Setup is 2 dovecot vm with nfs storage (distinct server each) (debian jessie 8.9 + backports) about a thousand mailboxes receiving an average of 18K mail daily

here is the dovecot -n for both server:
