You can add it in to a running ovirt cluster, it just isn’t as
automatic. First you need to enable Gluster in at the cluster settings
level for a new or existing cluster. Then either install/reinstall your
nodes, or install gluster manually and add vdsm-gluster packages. You
can create a stand alone gluster server set this way, you don’t need
any vddm packages, but then you have to create volumes manually. Once
you’ve got that done, you can create bricks and volumes in the GUI or
by hand, and then add a new storage domain and start using it. There
may be ansible for some of this, but I haven’t done it in a while and
am not sure what’s available there.

want to start over but would like the redundancy.

Just a hint -> use thin LVM if you wish to use gluster snapshots (which is a nice
feature) .
I'm using gluster snapshots for my HostedEngine , as it is on a dedicated volume.
