Hi, I have OCFS2 Cluster of 5 nodes running on RHEL 5.2 (kernel version 2.6.18-128.1.10.el5). I am getting error like Jun 24 09:26:54 alf2 kernel: (2095,0):o2net_connect_expired:1637 ERROR: no connection established with node 2 after 30.0 seco nds, giving up and returning errors. Jun 24 09:27:54 alf2 last message repeated 2 times Jun 24 09:29:24 alf2 last message repeated 3 times Jun 24 09:30:54 alf2 last message repeated 3 times Jun 24 09:32:24 alf2 last message repeated 3 times Even local firewall (iptables) is stopped, just wondering why node2 (alf2) can't connect to itself. 'Service o2cb status' shows Driver for "configfs": Loaded Filesystem "configfs": Mounted Driver for "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster ocfs2: Online Heartbeat dead threshold = 31 Network idle timeout: 30000 Network keepalive delay: 2000 Network reconnect delay: 2000 Checking O2CB heartbeat: Active Can someone please help to fix this problem. I can these errors on other nodes also, nodes can't connect to itself. Thanks Raheel -------------- next part -------------- An HTML attachment was scrubbed...

Not sure why you think it is trying to connect to itself. o2net connects to other nodes only.
