Set the maintenance mode on the host and add GPU on a single cluster host

Error performing operation: unable to switch the host to maintenance mode.

There is no host that can run the engine virtual machine.

How can I set the host to maintenance mode?


You cannot use the WebUI to get a single host into maintenance mode.
What you can do is put the cluster in global maintenance mode, and shut down the hosted-engine.

From the host:
$ hosted-engine --set-maintenance --mode=global
$ hosted-engine --vm-shutdown

When you are done:
$ hosted-engine --set-maintenance --mode=none
$ hosted-engine --vm-startup
