Hi All,
I have tried the below command to migrate the data from the old
server(dovecot version: 2.0.9) to new servers(dovecot version: 2.2.36
(1f10bfa63)). But it's throwing an error.
old server name: production1
new server1 name: production2 (for HA/Replication)
new server2 name: production3 (for HA/Replication)
I have configured replication between production2 and production3, which is
working fine.
The issue is, the below command I am trying is from production2 server and
trying to take the data from production1 server.
-------------
[root at production2 log]# doveadm backup -a All -R -u kishore at
test.testorg.com
imapc:
dsync(kishore at test.testorg.com): Info: imapc(production1.testorg.com:143):

[root at production2 log]#

I looked into the production1 (old server) logs. I see the below error.
==============Jul 28 11:14:23 auth: Fatal: Master passdb can't have pass=yes
if there are
no passdbs
Jul 28 11:14:23 master: Error: service(auth): command startup failed,
throttling
==============
after the above error, I have commented "pass=yes" in production1 (old
server) server, then I see the below error.
===============Jul 28 11:17:10 auth: Fatal: No passdbs specified in
configuration file.
PLAIN mechanism needs one
Jul 28 11:17:10 master: Error: service(auth): command startup failed,
throttling
==============
Please suggest me on fixing the issue.
Adding the dovecot.conf configuration from old and new servers:

You've only supplied master passwords. You'll need # Contains master users credentials passdb { args = /etc/dovecot/master-passwd driver = passwd-file master = yes pass = yes } # Contains regular user credentials passdb { args = /etc/dovecot/passwd driver = passwd-file } Joseph Tam <jtam.home at gmail.com>
