Hello!, It seems the pve-devel mail list is not very welcoming or I am doing something wrong. I would try another angle: asking the users.
Is there any interest in having a storage plugin to integrate to FC Storage systems in a 1 vdisk = 1 LUN fashion?. That should allow you to offload some operations like cloning/snapshots operations to the specialized box. I'm currently testing an integration with Hitachi VSP, but it could be generalized to accommodate specific brand/model drivers (would assume Dell, HPE, Huawei, Purestorage are still selling similar systems) Regards.
