I've mounted a gluster 1x2 replica through NFS in oVirt. The NFS share
holds the qcow images of the VMs.
I recently nuked a whole replica brick in an 1x2 array (for numerous other
reasons including split-brain), the brick self healed and restored back to
the same state as its partner.
4 days later, they've become inbalanced. The direct `du` of the /brick are
showing different sizes by around 20GB. I can see at brick level how some
images are not the same size. I don't think this is normal, but I can't see
anything to point what could be the issue.
