Ok, after reading the log files again I found

I think that explains why the resource is not started on the other node, but I am not sure this is a good decision. It seems to be a little harsh to prevent the resource from starting anywhere, especially considering that the other node will be able to start the resource.
Cheers,
Jens

Hi,
> Would "rmmod <interface-driver-module>" be a better hammer of choice?
I am just testing what happens in case of hardware/network issues. Any hammer is good enough. Worst case would be that I unplug the machine, maybe with ILO.
I have created a simple testing setup of a two-node cluter with a virtual ip and a ping resource which should move to the other node when I unload the drivers on the active node. The configuration is
MDA1PFP-S02 10:02:53 1203 0 ~ # pcs cluster setup --name MDA1PFP MDA1PFP-PCS01,MDA1PFP-S01 MDA1PFP-PCS02,MDA1PFP-S02

When I now unload the drivers on the active node the VIP resource is stopped but never started on the other node although it can ping.
