Thanks for the suggestions everyone. First up, no, this is not part of a Gluster HCI.
Secondly, "Confirm Host has been rebooted" seems to require the host have a status of "Non operational", "Maintenance" or "Connecting" from the error pop up. Ah, as I'm writing this, I shut down the host and now the status changes to Non-responsive and lets me put it in maintenance so I can remove it. So it looks like the change in config causes the engine to not be able to communicate with the host. Is that a bug or expected? What should my workflow have been here after reinstalling the node? Thanks, Shareef.
