Why not use qcow2 format over generic NFS? It will give you shapshot-rollback features and I don't think that with much worse speed than these features on ZFS level. But on my experience, NFS storage for VMs is bad idea: it causes huge latencies under load, leading to chashes. If you want

Don't get me wrong. Of course NFS works fine, but it is a "stupid" file storage. It would be great to have snapshot/rollback features from the Proxmox PE gui. The ZFS commands should be executed transparently on the storage, so that you can have a "virtual" ZFS that can be used in a cluster. I

Hi, How is this different from a normal NFS share that Proxmox already supports using? [1] ZFS processing would happen on your shared storage NAS server where you are exporting the NFS share from. All Proxmox sees is an NFS share located on another machine, and remains ignorant to the
