Hi Guy I was curious, what problems did you have with heartbeat? I've been having a strange problem where the LB node, using Xen, where I keep loosing the ability to see the HAProxy stats page. If I stop and restart Heartbeat, then the stats come back for about 15-20 minutes. The failover capabilities seem to keep working, I just loose the stats. I also looked into pound, but I was concerned because others said they had problems on a busy CMS site. When I started to set this up, I looked at DRBD VS rsync/replication, but I actually don't remember now why I chose against it.

I'm trying to keep things as simple as I can, so what is the correct way for me to handle this? Another option is to have Pound (http://www.apsis.ch/pound/) doing your HTTPS proxying. It does the SSL authentication and then sends the request for the actual content to the backend servers. Not sure of performance if you've got a site with very heavy traffic though. I'm currently using HAProxy and Pound side by side for my web load balancing and it works just fine with webmail servers that get a fair bit of traffic. On the subject of load balancing, I'd be careful about going the Heartbeat route. I've used it before and had headaches. I was using it with DRBD though, so it may work just fine in your situation. Cheers Guy
