I currently have a new setup running ovirt 3.3.3. I have a Gluster storage
domain with roughly 2.5TB of usable space.  Gluster is installed on the same
systems as the ovirt hosts. The host break down is as follows

Ovirt DC:

4 hosts in the cluster. Each host has 4 physical disks in a RAID 5. Each
disk is 500GB. With the OS installed and configured I end up with 1.2TB of
usable space left for my data volume

Gluster volume:

4 bricks with 1.2TB of space per brick (Distribute Replicate leaves me with
about 2.5TB in the storage domain)

Does this setup give me enough fault tolerance to survive losing a host and
have my HA vm automatically move to an available host and keep running??
