Yes, we changed it to a 3 host setup only and removed the possibility to
add more hosts in the initial setup.

Please proceed with 3 servers, and then add the remaining 3 to the cluster
from the oVirt UI.

You can add additional gluster volumes from the 3 new servers and create
new storage domain.

If you want to expand the gluster volume that was created in the initial
setup (i.e add new bricks to it) - it's advised to add bricks while there
are no VMs running (this is if you're on a gluster version =3.8, as there's
a bug with rebalance with ongoing I/O)

Yes, leave this blank
