I'm having problems deploying GlusterFS to an Origin cluster.
I have 3 identical nodes for running glusterfs, but the deployment seems
to randomly fail on one of the nodes sometimes. This is a typical error
(with the json reformatted). Notice how node 001 and 003 work fine, but
002 fails.
All three nodes are equivalent in config.

Any idea what's going wrong?
