Hi all, FYI, I recently released Subprovisioner [1], a qemu-storage-daemon-powered Kubernetes storage provider that enables users to provision block volumes backed by a single underlying shared file system. It works by storing those volumes as qcow2 images and exposing them as block devices using qemu-storage-daemon. This also allows it to support features like volume cloning and snapshots efficiently, by creating overlay images.
A solution like this can be useful, for instance, when one would like to use a single big NFS share as storage for a Kubernetes cluster. It's also an interesting use case for qsd. Thanks, Alberto Faria [1] https://gitlab.com/subprovisioner/subprovisioner
