Hi, junxiao!
We can't find correct fencing log after a node fencing itself.
We know there is log such as following in source code:
printk(KERN_ERR "*** ocfs2 is very sorry to be fencing this "
"system by restarting ***\n");
But we NEVER found this message from /var/log/message or last "demsg".
Do u mean we can find this message from local fs log after applying this patch
set?
Or any way to find this output (without netconsole), thx?

Subject: [Ocfs2-devel] ocfs2: o2hb: not fence self if storage down
Hi,
This serial of patches is to fix the issue that when storage down,
all nodes will fence self due to write timeout.
With this patch set, all nodes will keep going until storage back
online, except if the following issue happens, then all nodes will
do as before to fence self.
1. io error got
2. network between nodes down
3. nodes panic
