+++ This bug was initially created as a clone of Bug #1395498 +++

Description of problem:
Basically our glusterd service would not start on Ubuntu 14.04.
Logs kept saying some old;
http://paste.ubuntu.com/23483365
Management volume was same as 7 other machines that were online in our network.

Version-Release number of selected component (if applicable):
gluster 3.8.5

How reproducible:
Okay so the issue we found that in this servers /var/lib/glusterd/peers file
for another server, there was a blank space line.
Whilst this existed, it would not start the service.
We have no idea where this came from suddenly, service had been working since
the upgrade to 3.8.5 5 days ago.


Expected results:
If there is a commented line in these files or a blank space, it not to fail
starting the service.


Additional info:
@JoeJulian advised to lodge a bug after I managed to fix it

Basically when I did a 
cat /var/lib/glusterd/peers/*

It looked like this

Issue is not getting reproduced after multiple trials with latest code base,
hence closing the issue.
