It's only "far from good" for certain use cases, not all. I'm actually quite pleased that GlusterFS emphasizes C & P over A and none of my users complain ( I use raw images for 14 kvm vms on one of my GlusterFS volumes ). Those VMs mount GlusterFS volumes for their application data. Very little is done on the raw image. Not everybody that uses virtualization is going to be marketing those VMs to 3rd parties that expect it to pretend to be an isolated system.
