This is a little off the typical discussion found on the list, and I apologize in advance for the slight interruption. I'm looking for anyone who has used LVM and Sistina's GFS to implement a clustered mail server environment using commodity PCs. I use the term cluster here, somewhat loosely, to describe multiple machines providing the same or similar service(s), in this case mail services (pop, imap, webmail, smtp). I'm particularly interested in your use of LVM/GFS in implementing a shared mail store/filesystem. If you have such a setup, and could spare a few moments, I'd like to pick your brain on your cluster configuration and experiences. Feel free to reply to the list or directly. Some of the things I'd like to know are: Describe your config, number of machines, adapters, disk subsystems (manufacturer would be helpful for adapters and disk subsystem). Software you're using to provide mail services? (sendmail, qmail, cyrus, courier, squirrelmail, etc.) How many users do you serve? How did you decide to distribute workload? RR DNS? Split services among machines? Linux Virtual Server? Something else? Do you share more than the mail filesystem among machines? If so, what? Do you have any performance numbers? What snags did you hit? If you had to implement again, which would you choose: "big box" or the cluster? Anything else you'd like to volunteer. Thanks in advance, Scott -- Scott Parish, Systems Administrator, Pittsburg State University Thinking is the hardest work there is, which is probably the reason why so few engage in it. - Henry Ford _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
