I have a customer that is planning to relocate half of their 11 node cluster to a different rack. They are using less than 50% of the cluster resources and they are asking if this is something that can be done online. I'm pretty sure that I know the answer to this question but wanted to double check.Can they move 5 (of 11) nodes without impacting productions, since they are using less than 50% of the resources?
Can we temporarily remove nodes from the cluster and then re-add them after the move?

Yes, you can remove the nodes from the cluster.
Anyways, you can remove single node at a time so you can assess the cluster resiliency status before you remove a node from the cluster.
