Description Joe Julian 2013-04-11 15:09:45 UTC
Description of problem:
Two people were individually complaining that glusterd would silently end. Looking at the logs, there was no indication why.

{all normal start up lines above, including the rest of the confusion causing "Unknown key" list}

Version-Release number of selected component (if applicable):
3.3.1

How reproducible:
Always

Steps to Reproduce:
1. Truncate a file in /var/lib/glusterd/peers
2. start glusterd
  
Actual results:
glusterd silently fails with no indication what's wrong.

Expected results:
glusterd should throw an error explaining why it's dying.

Additional info:
I don't know how the peer files can get into an empty state. I believe this has something to do with adding new peers.
