Just wondering if there is a possibility of reload only the Master from the MX100 cluster that I've got in production, I did my research and I did only get the typical reboot option in the dashboard and that will reload the whole cluster.
The spare becomes the master while the primary is rebooting, but it takes over as master again when it has finished rebooting.
Can be annoying for some things like client VPN. Users get disconnected on the primary reboot. If they then reconnect again, they connect to the spare but then get disconnected again once the primary has finished rebooting.
