Not sure I would raise something here; if the admin did put the node in maintenance while chef-client was running, then, well, that's the way it is and why should chef fail because of that?

Yeah OK, I guess a Chef::Log.warn is more appropriate here.

The reasoning is explained in the comments. I'm not sure why I ever thought it was a good idea to allow a chef-client run to proceed if maintenance mode is set. It's not even as if that approach could ever restore an ill node to full health, because we were deliberately checking whether the maintenance mode was set prior to the chef-client run, and if so, leaving it set. This way, if a node is left in maintenance mode, it will be discovered sooner, resulting in the cloud operator being alerted to a degraded cluster sooner.

Crap, raising an exception in the start handler doesn't abort the run :-( Need to find a way to do this. |
Make #maintenance_mode? return a sensible value even when Pacemaker is down or uninstalled. This is especially helpful when it is invoked by Chef's start_handler. Cherry-picked from crowbar/barclamp-pacemaker@7dff6c1.

Also ported crowbar/barclamp-pacemaker#149 on top of this.
