I'm trying to set up replication between two servers and I've hit a snag. I have two users and am using mbox files. If anybody has a sample config file for a simple system like mine I would really be grateful to see it.
Thanks,

I've got it working more or less. I had to change the mode of replicator-doveadm to 0666. I'm still getting errors for 'nobody' but that doesn't seem to cause it to not work, just annoying.
Can anybody explain the significance of the mode?
I'm syncing between a 2.2.9 and 2.2.13 system. Any thing I should look for?
Thanks,

Well it worked fine until yesterday and then it started creating duplicates by the hundreds. Errors about EOF for two valid users on the secondary system. This is a sample of the errors in the log:

I disabled replication and don't really know where to go from here. Can anybody give me a hand?

From what I have seen in this thread your configuration looks ok to me.
IIRC, you have two users, only. And, IIRC, the mbox format isn't really suited for replication. Thus, I do recommend to migrate to another mailbox format like mdbox or sdbox. Migration can be achieved by dsync. You will find examples in the archives of this mailing list.
Good luck, Michael

You can add to conf.d/10-mail.conf
first_valid_uid = 1000 last_valid_uid = 2000
You have nobody uid 65534 so make last_valid_uid less than you have in your /etc/passwd. Same thing with the first_valid_uid just pick first uid after users start in your /etc/passwd
I don't know why the user 'nobody' shows up here? nobody is in the /etc/passwd file but he has no group.

Replication attempts to replicate all the users returned by userdb iteration. So you need to make sure that:
doveadm user '*'
doesn't return any extra users you don't want replicated, such has "nobody". Setting the first_valid_uid and last_valid_uid to exclude the unwanted users should have solved this problem (verify that the above command doesn't return "nobody"). I think the problem you have now is simply that replicator already remembered the "nobody" user and doesn't get rid of it automatically. So remove it with:
doveadm replicator remove nobody

Thanks, running doveadm replicator remove after setting the first/last uid did solve that issue. Maybe you would take a look at the other errors I'm getting? Nothing has changed in the configurations from the previous posts in this thread. If you need any more information please let me know. Thanks!

I think the problem you have now is simply that replicator already remembered the "nobody" user and doesn't get rid of it automatically. So remove it with:
doveadm replicator remove nobody
Thanks, running doveadm replicator remove after setting the first/last uid did solve that issue. Maybe you would take a look at the other errors I'm getting? Nothing has changed in the configurations from the previous posts in this thread. If you need any more information please let me know. Thanks!

Thanks Edgar, I hadn't seen that page before. I've tried every combination of locking but still get the same errors.
I would love to see somebody's config files that has this working on a Ubuntu server.
Thanks,

Hi Knute,
here are my dovecot config's. It seems to be somehow sometimes for me. I am not expert of dovecot just started few weeks ago. I have been playing around and I am not sure what makes mine to work.
I have 2 similar configured servers. Config's are not identical. I had problem with notification "Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied." Still not working perfectly. Replication worked when I used that users UID in "service aggregator" and "unix_listener replication-notify." Then the other user was failing ....
I am using only imap part and haven't test other protocols if they work or not. The other protocols like pop and sieve came by default. I didn't bother to remove them.
#doveadm sync -A remote:u15dove2 command will sync things but I still have some problems. Hopefully this might get you to correct track.
One more thing. I copied root's ssh keys as authorized_keys so I can ssh -lroot other machine without password and visa verse.
So sorry no perfect solution yet avail ....
