Thanks for the shout out. If you have test environments, I'm happy to
add other platforms that expose APIs to automate.

I have personally never worked with a Hitachi storage (only HP, 3PAR, NetApp and Dell), but the functionality you describe is exactly where I’d shout “yes, I want it too”.

All it would require is proper layout on the storage side. If a LUN (or more LUNs) is dedicated to a VM, then you need to freeze the writes in a VM for a little and call the API of the storage to snapshot the LUN. Removal of a snapshot would be fully transparent. Where it gets more complicated is an app-aware snapshot. And revert to a snapshot, that would have to be done very carefully, nodes should not start panicking that they lost storage. Is this what you meant?
