In a two-node setup, node 0 will survive, because that's the node with the lowest node number (as defined in cluster.conf).
You may want to think about adding a third [FAKE] node; if this is a feasible workaround, then only the troublesome node should fence itself. -----Original Message----- From: ocfs2-users-boun...@oss.oracle.com [mailto:ocfs2-users-boun...@oss.oracle.com] On Behalf Of Alain.Moulle Sent: Tuesday, February 08, 2011 3:06 PM To: ocfs2-users@oss.oracle.com Subject: Re: [Ocfs2-users] Question about eth communication for ocfs2 Hi, I have give it a try : linkcom PtP between node1 and node2 IO traffic on OCFS2 on both sides unplug the PtP cable from both nodes =>both IO traffic on OCFS2 are stalled =>after a short while, node2 self-fences, =>whereas a short while after the self-fence of node2 , IO traffic on node1 starts again So in fact, you confirm that there is no "slave or master" question around this self-fence, but it will always be the larger node number in /etc/ocfs2/cluster.conf which will self-fence ? Thanks for your confirmation.
