Oops. So there's an on_fail=fence for this monitor operation.

Should monitor operations keep running even > though the resources are set to is_managed=false? Yes. There was some discussion about it and the majority of votes went this way, i.e. that monitoring should continue even for the unmanaged resources. > Is explicitly setting > the monitor operations to disable=true the "right way" to prevent > unwanted fencing actions during cluster maintenance? I'd say yes. But note that I was also in favour of having monitoring disabled by default.
