[ovirt-users] new cluster, 6 nodes

Hi all, planning a new 6 node hyper-converged cluster. Have a couple of questions 1) storage - I think we want to do 2x replicas and 1 arbiter, in the chained configuration seen here (example 5.7) https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5... any suggestions on how that looks from the bottom up? for example does each host have all their disks in a single hardware raid6 volume, and then the bricks are thinly provisioned via LVM on top so each node has 2 data and 1 arbiter bricks. or is something else recommended? 2) setup - Do I start with a 3 node pool and extend to 6 or use ansible to set up 6 from the start? Thanks
