When I set local maintenance on the self-hosted engine hypervisor host through the manager GUI it becomes stuck in state "Preparing for maintenance". The hosted engine virtual guest is automatically migrated because the HA broker is successfully set to maintenance mode=local. The host returns to state "Up" in the manager if I press button "Activate", but the column "Virtual Machines" continues to count the migrated VM. If I then reboot the host it reverts to state "Up" and the VM count no longer includes the vacated hosted engine, so I'm guessing it never *really* achieved state "Maintenance" even though the event log claims so immediately after the button is pressed. The condition persists after the reboot if the then-current hosted engine hypervisor host is again assigned to mode "Maintenance". I'm running 4.0.1, and I've tried restarting services and rebooting the hosts and VM involved. I suspect it has something to do with my other thread about the locked storage domain.
