You're deliberatly causing a split-brain by doing this. The correct way to simulate a node failure is (really) to yank the power cables, or otherwise STONITH the node. If you want to test fail-over between the nodes, you can use the hb_standby and hb_takeover commands to perform a graceful fail-over.
