With a simple client on the node to be fenced and always returning success ... Unfortunately it probably won't work in most of the interesting cases as either the to be fenced node isn't gonna be alive enough or connectivity is gone. Or is it possible to make the remote-management (aka fencing-device) talk to the display somehow to display a configurable text. Going with an alert agent or registering for fence-history (history would be reported on all nodes - thus no need for additional communication) probably isn't gonna be helpful either as I think you can't see partial success on a topology - just when it is reported to be finally killed - well to late then to do something on the node to be killed :-( Klaus > > Regards, > Ulrich > > > > _______________________________________________ > Manage your subscription: > https://lists.clusterlabs.org/mailman/listinfo/users > > ClusterLabs home: https://www.clusterlabs.org/ > >
