After Joe's suggestion I went ahead and used the functionality of Cloudmin/Cloudmin services and I can not get the servers to cluster slaves right. On one of the VM's, I get the following:
Adding carbon32.coolservers.com .. Server carbon32.coolservers.com is not running Webmin version 1.202 or above.
I could only find one reference to this on Google and none here. The post I found in the Google response was of no use - closed by someone on the team here.
Can anyone tell me why I am having this version issue? For goodness sakes, Webmin in that container is 1.810! Am I going to have to install this stuff again? I am so sick of running into different fatal issues with Cloudmin/Webmin/Virtualmin, I could scream. I said long ago I had some notions of contributing to the project with features through new code/modules, but I want no part of adding functionality to something that is "broken" in number of ways.
For instance, to make all of the servers available to be added as a DNS cluster server, you have to delete all of the Webmin Servers Index machines and add them back in one at a time, then going to the Cluster DNS server setting, otherwise not all of your servers are going to be available for you as an option in Cluster DNS servers.
I could go on and on, but there is no point. I am just right now trying to find the bug is producing the error and ensuing failure in Cluster DNS Servers in Bind.
