It's nice to know someone else out there has these questions as well.  What I'd really like confirmation on is basically this:  In a JBOD oVirt HCI configuration with multiple disk devices per host node is it possible to have just one data volume or is it necessary to create multiple data volumes (one or more per each physical disk you want to store vm data on)?   Meaning if I had 4 JBOD disks in each node and I wanted VM data to be stored and accessed on all 4 would I need to create 4 different data volumes (one per disk).  And if so would they have to have unique names and brick dirs/mount points?
