A gluster volume cannot span multiple clusters. If you want to create a separate cluster with the Broadwell nodes, then create a new gluster volume using the disks from these nodes - i.e do not expand the existing volume by adding bricks from the new servers.

About this: why?

I mean, from the new cluster I can spawn a VM based on an image stored in the other cluster domain and it works. What's the problem?

Anyway I created a new data domain for that cluster
