For gluster-block it may be easier to have snapshot support in tcmu-runner instead? The qcow2 format would be ideal, and is in use by different Virtual Machine approaches running on Gluster already. There even is an upstream issue open for it: https://github.com/open-iscsi/tcmu-runner/issues/32 Contributing towards this might be quicker than implementing file snapshot support in Gluster? Niels
