Subject Re: Resource Partition Failure

That sounds more promising. Does disabling a partition trigger ideal 
state computation to rebalance the cluster?

Ideally it would be great if the corrupted instance could move itself to 
the ERROR state which was then reset by possibly the controller. Is that 
possible?

Is there a way to tell helix that that partition of that resource needs to "fail" without
killing the whole node and hence destroying all other resources on that machine?
