Dear colleagues, Thank you all for all your yesterday's help. Alas, I had to reboot both nodes about 5am, because the situation has gone critical. Now I built almost the same cluster in a lab. Its configuration is REALLY simple: <?xml version="1.0"?> <cluster name="cluster1" config_version="1"> <cman two_node="1" expected_votes="1"/> <clusternodes> <clusternode name="vlan201.eth0.host1.lab.***.net" votes="1" nodeid="1"/> <clusternode name="vlan201.eth0.host2.lab.***.net" votes="1" nodeid="2"/> </clusternodes> <fencedevices/> <rm> <failoverdomains/> <resources/> </rm> </cluster> I started iscsi, cman, clvmd, gfs2 and rgmanager. When I'm disconnecting a node, the second node can't work with the same filesystem: any attempt to open some file just waits. But when I'm reconnecting the node back, files are opening and all is working. I'm sorry if it's a noob's question, but why does it ignore "<cman two_node="1" expected_votes="1"/>"?
