Each machine is running pop and smtp, and they are all "balanced" 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 (not enough $$ for a NetApp Filer...). Each of these machines has two disks mirrored running vinum (for a separate thread, 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? I'm thinking of just using a simple rsync script locally on each machine, and then un-mounting / re-exporting / re-mounting file systems, but this seems - well, complicated. Any thoughts / ideas / criticisms welcome. Thanks! Brian -- brian.jackson@third-rail.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
