I see I have a very unfortunate typo in my previous mail. As supported by the vm-status output I attached, I had set --mode=global (not none) in step 1.

I am not the only one experiencing this. I can reproduce it easily. It appears that shutting down vdsm causes the HA services to incorrectly think the system has come out of Global Maintenance and restart the engine.

This output shows that the lockspaces are still acquired. When you put hosted-engine
in maintenance they must be released.
One by directly using rem_lockspace (since it's the hosted-engine one) and the other
one by stopMonitoringDomain.

I quickly looked at the ovirt-hosted-engine* projects and I haven't found anything
related to that.
