The network connect is failing. Could be because of a firewall, or bad ip address, some switch issue.
Mount the volume on node 2. Then enable tracing and tail messages file. # debugfs.ocfs2 -l TCP allow # tail -f /var/log/messages Then from node 4, ping node 2 using netcat. # nc -z 192.168.1.2 7777 If it succeeds, then you should see: Connection to 192.168.1.2 7777 port [tcp/cbt] succeeded! Additionally, you will see a message on node 2 "attempt to connect from node...". If not, then look at your network setup. Remember to disable tracing on node 2. #debugfs.ocfs2 -l TCP off Sunil Chris Clonch wrote: > We are testing clustering and I am having issues getting all of my > nodes to mount. I have 4 nodes.
