I have been googling but couldnt see any concrete answer Is it possible to load balance multiple cyrus imapd connections with multiple servers connecting to same common storage Say , I mount the /var/spool/imap and /var/imap and the sieve dir from a SAN box on 2+ servers, Any user trying to access his mailbox will connect to any server using a h/w load balancer Irrespective of which server he connects to he will always see the same mailbox Is this a feasible solution. Will it not create locking issues on the mailboxes.db How many imap processes can a single mailboxes.db handle If I want to give a zero delay response. If there is requirement for more mailboxes , I just add more frontend boxes behind the load balancer. Can this work ?
