> However when trying to create the image with qemu-img create I get an unknown protocal error. What errors are you getting? What cache mode are you using for qemu images? What is the backing filesystem on your gluster bricks? [ext4, xfs, etc] I'm troubleshooting a problem (https://bugzilla.redhat.com/show_bug.cgi?id=958781) with xfs backed filesystems + KVM/qemu and I'm wondering if you are getting the same errors. -Jacob
