Upgrading to High Availability.

Hi everybody.

We're currently running a single server with Virtualmin 4.16.gpl, and we're getting to the point where it's becoming necessary to implement some high availability measures.

The plan I have so far is to set up a Gluster cluster (that part's done), build a second Virtualmin server, and then place a Zen (not Xen!) load balancer in front of all this to handle outages. So far, this seems like a good plan, but at the same time, I have no actual experience doing any of this, so I could be very badly mistaken here.

At any rate, the problem I now have is synchronizing the configuration of both Virtualmin servers. I recall that this is a feature somewhere in Virtualmin, but do we have to get a Pro license first? I can't find anything about it in the Virtualmin panel, and I haven't found much about it in the documentation. Maybe I just don't know where to look?

I could use a little help in this.
