At the moment, we didn't use this feature on our cluster => all the queues can use resources from all the nodes.
Now, I would like to restrict one queue to a subset of nodes (this nodes having particular rights on our network).
In other words, I would like that my previously existing queues continue to use resources from all the nodes of the cluster and that only the new queue is restricted to a sub set of nodes.
I've read around node labels feature, but I'm wondering about one detail :
From what I understood, one node can be assigned only one single label => as soon as I will associate "mylabel" to a subset of nodes, these nodes will not have the "default" label anymore, right ?
My question is about all the queues that already existed in our configuration : will they be able to use resources from all the nodes (option 1) or only from the "default" labelled ones (option 2)?
Must I define "mylabel" as "non exclusive" label to fit with option 1 ?
