[Ocfs2-devel] ocfs2: o2hb: not fence self if storage down

[Junxiao Bi]

Hi Mark,

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
