Hi all,

I am still struggling with this issue.
I scraped my previous configuration and started from beginning.
Thanks to Aki Tuomi and his suggestion I changed the users in my
configurations from vmail --> root and that helped.
Now I have a working replication but with some problems and strange
behavior.
Replication works only when I manually execute a command:

"doveadm sync -A tcp:secundary:server:12345"

Automatic fast and full sync do not work:

doveadm replicator status "*"
username
 priority fast sync full sync success sync failed
zdokman
none 01:46:14  01:46:14  01:46:14 -

doveadm replicator status
Queued 'sync' requests0
Queued 'high' requests0
Queued 'low' requests 0
Queued 'failed' requests  0
Queued 'full resync' requests 0
Waiting 'failed' requests 0
Total number of known users   1

doveadm replicator dsync-status
username
  type status

 -Not connected

maillog has no error entries.
my conf files are attached.

I don't understand why is this happening and how to fix it, any help is
much appreciated.

Best regards,

Your problem is that you are running service doveadm as vmail, but you
are using real uids. You need to start doveadm server as root to be able
to switch into the correct target user.

Potfix+Dovecot with dsync replication problem

[Zeljko Dokman via dovecot]

Hi all,

I am in need of some help.

Straggling to make something work, trying to configure postfix and dovecote
imap server with dovecote replication.

Can’t figure out what is wrong with my configuration.



Replication is working only for vmail user account, I am getting this error
on my secondary server  for all other users…



dovecot: doveadm: Fatal: setgid(4015(zdokman) 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
4015(zdokman) instead of 5000(vmail))



primary server reports this error:



dovecot: doveadm(zdokman): Error: doveadm server disconnected before
handshake: EOF

dovecot: doveadm(zdokman): Error: sync: Disconnected from remote: EOF





doveadm replicator status '*'

username
 priority fast sync full sync success sync failed

vmail
none 01:58:13  02:05:25  01:58:13 -

zdokman
 none 00:00:25  02:55:26  -y

test
  none 00:01:00  21:48:13  -y



doveadm sync *

doveadm(root): Fatal: execvp(Maildir) failed: Permission denied

dsync-local(root): Error: read(remote) failed: EOF (version not received)



I am attaching my dovecot.conf main.cf and master.cf.



I think my problem is with permissions  but I can figure out how to
workaround it.
