Probably maintainance-mode also tells the cluster-manager to completely
stop monitoring.

Its un-managed, not un-monitored ;-)
Actually this is not a problem, it will monitor as long as the service
is up. As the first monitor-action fails, the resource is marked as
"failed" and no more monitor action is run. Until you explicitely ask
for it with "cleanup <resource>" or "reprobe <node>".

Have fun,

Arnold
