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.
2) I'm using a separate VLAN+domain name for gluster, and oVirt

You can add hosts using the Add new host flow - and provide the FQDN that
you want as management interface, and later associate the gluster VLAN with
a network that has "gluster" role.
Please keep in mind that you cannot add this to a new cluster in oVirt if
you have already used bricks from these servers on existing volume in
another cluster
