<p class="MsoNormal">Sheepdog should handle the total node failure, but I think some bugs<br>
still exist in it. The error handling has not been tested enough.<br>
<br>
If you have not cleaned the damaged cluster yet, can you give me the<br>
outputs of "collie cluster info" on all the nodes? Those info would<br>
be helpful to find the error reason.<br>
<br>
I'm implementing a "collie cluster check" command, which works like<br>
fsck for Sheepdog. This command would be helpful for recovering the<br>
damaged cluster.<br>
<br>
<br>
Thanks,<br>
