The host moving to Non-Operational state with error "Gluster command 
failed..." is dependent on whether "Enable gluster service" is checked 
on your cluster. This check indicates that you also want to manage 
gluster storage provisioning on the nodes.

A recent change now checks that vdsm-gluster support is available for 
such clusters. That's probably why you are seeing this error after update.
