[Gluster-users] QEMU-KVM-libgfapi question

I am running a KVM test cluster on Fedora 19 using gluster + libgfapi as
a network backend for my QCOW2 images.
This configuration precludes me from using virsh's backup features
provided in Fedora and thus I am doing "live snapshots" by executing:
# perform internal snapshot on qcow2 using FUSE mount to gluster:
qemu-img snapshot -c snapname /gluster/test.qcow2
# convert the snapshot to an external file for archiving:
qemu-img convert -s snapname /gluster/test.qcow2
1. Is there any blocking or locking issues I should be concerned about
while doing snapshot's or converts?
2. I know this leaves my snapshot in an inconsistent state...but is this
an incorrect use of the qemu/qcow2 tools?
3. Is there a better way to do this via gluster / gfapi that I'm missing?
