Thanks Andrew, I'll try this workaround tomorrow for sure. But reading though that bug report (closed not a bug) it states that the problem should only arise if something is not releasing a sanlock lease. So if we've entered Global Maintenance and shut down Engine, the question is what's holding the lease?
How can that be debugged?

While searching for my issue of wdmd/sanlock not shutting down, I
found this which may interest you both:
https://bugzilla.redhat.com/show_bug.cgi?id=888197
Specifically:
"To shut down sanlock without causing a wdmd reboot, you can run the
following command: "sanlock client shutdown -f 1"
This will cause sanlock to kill any pid's that are holding leases,
release those leases, and then exit.
