Hi everyone, I've currently built an e-mail cluster with three machines running FreeBSD (and qmail, obviously). Each machine is running pop and smtp, and they are all accessed in a more or less "balanced" fashion using round robin DNS. One of the machines is exporting it's /usr/home directory, and the other two are mounting this directory on their /usr/home, so that no matter which machine you hit you get your mail. Each of these machines has two disks mirrored running vinum (for a separate list discussion, yes you can have two disks mirrored running vinum and boot off either...), but I'm paranoid - what happens in a catastrophic situation where the machine exporting /usr/home goes away? Has anyone done anything similar? And how do you handle replication of mail between "primary" and "secondary +N" machines? I'm thinking of just using a simple rsync script locally on each machine, and then un-mounting / re-exporting / re-mounting file systems in case of failure, but this seems - well, complicated. Any thoughts / ideas / criticisms welcome. Thanks! Brian -- [EMAIL PROTECTED]
