It looks like we are experiencing a bug in the version of glusterfs
included with ovirt 4.2.3. It looks like glusterfs 3.12.x has an issue
where it consumes large amounts of ram which has caused our HV report
storage errors and pause VMs.
https://bugzilla.redhat.com/show_bug.cgi?id=1496379
Is there a safe way to get glusterfs-fuse v3.13.x installed with ovirt
4.2.3 or do we have to live with this issue until future updates to
ovirt/glusterfs are released?

We see this same issue occur on all hv in our cluster.
