correct. a new server will NOT add space in this manner. But the original Q was about rebalancing after adding a 4th server. If you are using distributed/replication, then yes, a new server with be adding a portion of it's space to add more space to the cluster. But in a purely replica mode, nope.

Wait, in a distribute-replicate, with replica count 3, adding a fourth server doesn't add space..... I can't add a fourth server, I have to add 3 more servers (due to the replica count)
