Dave has more details, but we needed to add an API to give ring id
information to fenced to prevent fenced from entering a stuck state.
The conditions leading up to the problem are difficult for me to recall,
but it did happen in community testing as well as internal validation.
I recommend pinging dct offline if you need more information.  (There is
a fenced patch that goes with this, and perhaps something else).

The configuration file should be the same on all nodes (so the latter).
 Must have been a 24 hr coding session prior to git commit :)
