I can confirm that doing an ifdown is not the source of my corosync issues. My cluster is in another state, so I can't pull a cable, but I can down a port on a switch. That had the exact same affects as doing an ifdown. Two machines got fenced when it should have only been one. --- Seth Reid

Hi, In our current design (which we plan to improve upon) we are using the CIB file to synchronize information across active and standby nodes. Basically we want the standby node to take the configuration that was used by the active node so we are adding those as resource attributes. This ensures
