Hello!
I need to "move" my one email server to new ip address. I wouldn't like
to make something crazy like dual gateway routing to achieve this.
So actually I have this educational idea to test it out and set up 2
qmailtoaster boxes to back each other up (replication) during the ip
changing phase.
What's roughly the idea how to have 2 identical qmailtoaster boxes (so
if I change the ip address on the DNS it will transparently change over
to new server with zero downtime to customers)?
I can have common mysql server for those 2 boxes, this is not a problem
(and i know how to set up mysql replication if i would ever need to have
separate mysql servers for additional security).
But will it work if I just keep db in sync and use NFS or glusterfs to
keep the same filesystem across the toasters (/home/vpopmail,
/etc/tcprules.d?)?
Is it correct that i need to have some files in sync from /var/qmail/?
Am I on the right track with my ideas at all?
