Im trying to setup Ovirt 4.3 RC because its the only one that supports AMD EPYC. The issue Im having is that I creates a raid 5 array of 5 120GB SSDs using mdadm and mounted it at /VM. I put the Host into maintenance, select Configure Local Storage, and it fails telling me:
New Local Storage Domain: Storage format is unsupported

I formatted the array to ext4. This is a self hosted system.  Anyone have any ideas?
