I have a new Load Balanced Pair with EV1Servers. They are running RHEL4, and they each have Plesk 8 on them. Before this, I have had individual servers with 1and1 running plesk 7.5, and ran the atomic-psa to keep everything up to date. I got the Load Balanced Pair so I could get some kind of high availability failover going in case I have to work on one server for maintenance, or backup/restore one server, etc. All my client's services would still be up, and they'd be able to upload, modify their dbs, check their email, etc.
Unfortunately, Plesk itself does not provide any sort of clustering functionality. So this seems difficult, and maybe not even possible. I've spoken with several people at EV1Servers, and they don't know of anyway to do this. They've suggested running Plesk on one server, then just rsyncing content to the second server. That keeps websites up, but email, dns, databases, etc would be down. Further, so would Plesk.
I'd really like my clients to be able to edit their Plesk content, like adding mail aliases, or adding databases, etc, and it would immediately modify the second server too.
On another forum, even someone said that ART has done this before somehow. Are there any third party addons, hacks, etc that can help facilitate a near high availability failover, with a pair of load balanced servers that have a private net between them for backend traffic?
Thanks in advance,
Kevin
