Hi.

I'm trying to set up a 3 node ovirt cluster with gluster as this guide describes:
https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1-and-gluster-storage/

I've installed oVirt node 4.1.2 in one partition and left a partition to hold the gluster volumes on all three nodes. The problem is that I can't get through gdeploy for gluster install. I only get the error:
Error: Unsupported disk type!
