I'm researching various high availability options for zimbra. I know Zimbra supports the Red Hat option, but I was looking at alternatives.
I see here - some people have gotten DRBD and Heartbeat working. Can anyone report Zimbra NE in production on DRBD / Heartbeat.
Has anyone tried Zimbra on GlusterFS with Heartbeat? I've been poking around on the glusterfs web site, and their cluster software looks interesting. I'm going to get a test env't up and see how it performs.
