Hello, I am running ocfs2 cluster with 2 nodes. Today, node2 restarted suddenly, and on node1 I found these logs: o2hb: receive negotiate timeout message from node 2 on region ... o2net: Connection to node node2 (num 2) at 10.1.2.14:7777 has been idle for 31.708 secs. o2net: Connection to node node2 (num 2) at 10.1.2.14:7777 has been idle for 30.720 secs o2net: Attempt to connect from node 'node2' at 10.1.2.14:49845 but it already has an open connection can somebody please explain what happened ? Even if there was short network interruption, the node was not supposed to restart. thanks,
