[Ocfs2-users] 2 Node cluster, and nodes OS hang

[Sunil Mushran]

tcpdump -i eth1 -C 10 -W 15 -s 10000 -Sw /tmp/`hostname -s`_tcpdump.log 
-ttt 'port 7777' &

Do this on both nodes before mounting on the second node. Ping me with 
the path to the logs.

I perform a basic mount, "mount -t ocfs2 /dev/ndas-00500435:0p3 /media/nas3". When I do this on the 2nd node..  after the 5 sec it takes to mount, the 2nd node will completely hang after 5 secs. I did see some local iptables blocks from the 2nd node. so I disabled the firewall on both nodes, and that did not help.
