This sounds very interesting. I look forward to trying it :)

(sorry for Outlook-affliction)

There's a fairly new feature in the crm shell with which it
is possible to edit the status section, e.g. to simulate a
resource failure or the node lost event. Then you can try
the ptest command (in configure) and it will show you what
would happen. This feature has not been complete at the time
when 1.0.6 was released and may still change.

Also, if you change the configuration and run ptest _before_
commit, that will also display the graph of what would
happen if the new configuration had been committed.

Thanks,

Dejan
