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
Each cluster is also created as a gluster trusted storage pool - that is nodes in the cluster are peer probed to each other. A gluster volume can only span one trusted storage pool at a time.
