[ovirt-users] Upgrade 4.0 to 4.1: Global Maintenance Mode not recognized

Hello, I upgraded one host from 4.0 to 4.1 without problems. Now I have a problem with another host, in another network, where the Global Maintenance mode is not recognized by engine-setup. Is there a way to force the setup or set the maintenance mode inside the database? One problem can be that an the host was accidentally upgraded to 4.1 before I upgraded the engine. kind regards gregor
