Hi! I think it's a common misconception that you can modify cluster resources while in maintenance mode: It seems the cluster expects the state it had when mainteneance mode was turned on later when you turn it off. Maybe it's like the airplane's autopilot: You can turn it off, fly the plane the way the autopilot would have done, and then when you turn the autopilot on again, the flight path will continue; however if you change direction while the autopilot is off, big confusion may arise when you turn the autopilot on again... ;-) Am I right? Still this doesn't explain where your configuration or log files went...
