title: How to add additional agents to mesosphere dc/os cluster?
body: <p>We have Mesosphere DC/OS version 1.7 running on 6 vmware vm's with rhel7 and we would now like to add more agents.  We were able to increase from our initial 2 agents(vms) to 6 agents(vms) by running dcos_generate_confg.sh --uninstall from the boot node. We then added the new ip addresses to the agent list in genconf/config.yaml and ran --genconf, --preflight, --deploy, --postflight.  This worked however the --uninstall blew away our existing public agent, which we had to go back in and re-install.</p>
  
  <p>Is there another way to add agents without running the --uninstall? Very nervous about what that's doing under the hood.  Thank you!</p>
