retrieves the overall space used by an instance on each of its nodes.
This can be used when balancing the cluster or checking N+1 status.

The flag is also exported in RAPI. Note the flag is currently broken for...

LUCreateInstance: only set running flag at the end

In lockless queries, it's better if we see the instance in ADMIN_down
