Dovecot HA/Resilience
Thank you Aki for the reply.
But I cannot disturb the version at present as it is a live server and
thousands of emails will circulate every hour.
Could you please suggest me how to create HA/resilience for the existing
environment. I have another server ready with the similar configuration.
Please provide any steps/link for me to proceed on this? It will be a great
help to me.
Thanks,
Kishore

Dovecot HA/Resilience
Thank you all for the replies....
I have the test environment with the same configuration. But I have been
asked to go with same environment for HA/Resilience in Live.
Yes, I have only one Live server. It is configured in "Maildir" format. The
data stores on a Network / Shared Storage (But definitely not local disk,
its a mount point).

Migration from one server to 2 new servers
Hi,
But there is no "doveadm backup" option in dovecot 2.0.9 version.
[root at production ~]# doveadm -backup
doveadm: invalid option -- 'b'
[root at production ~]# dovecot --version
2.0.9
Copy the contents by using "scp", will that work?
Thanks,

Dovecot HA/Resilience
Also you should probably use dovecot director to ensure same user sessions end up on same server, as it's not supported to access same user on different backends in this scenario.

Migration from one server to 2 new servers
I tried this command also. It didn't work. It shows syntax again. Please
see the supported commands in dovecot 2.0.9 version. This doesn't support
replication also as per syntax, if i am not wrong. Please suggest me.

Dovecot HA/Resilience
If you just want active/standby, you can simply use corosync/pacemaker as other already suggest and don?t use Director.
I have a dovecot HA server that uses floating IP and pacemaker to managed it, and it works quite well.
The only real hard part is having a HA storage.
You can simply use a NFS storage shared by both servers (as long as only one has the floating IP, you won?t have issue with the

Fwd: Load balancer for dovecot servers - Not able to send emails
Hi John,
Thank you for the reply. Actually it was setup like this by another
member, who left the team/company recently. Now it came to me to handle
that responsibility. That's how I got in to this. At present I am not able
to migrate/upgrade immediately. Because it sends emails around 100K+ emails
everyday and I do not want to disturb that.
Coming back to your question, Actually the
