I'm building a 3 host HCI configuration. I have servers configured and latest version of oVirt node 4.2 installed. I'm preparing to run the cockpit hosted engine + glusterFS deploy. Each of my hosts have two SSDs in JBOD /dev/sda and /dev/sdb Currently these drives have not been touched, formatted or mounted. Is this required before continuing with the deploy, or will the deploy script format and mount the drives accordingly? Thanks!
