<div> </div>
<div>This serial of patches is to fix the issue that when storage down,</div>
<div>all nodes will fence self due to write timeout.</div>
<div>With this patch set, all nodes will keep going until storage back</div>
<div>online, except if the following issue happens, then all nodes will</div>
<div>do as before to fence self.</div>
<div>1. io error got</div>
<div>2. network between nodes down</div>
<div>3. nodes panic</div>
<div> </div>
