Why VM-level snapshots on FC storage, when nowadays these s= torage boxes are smart enough to do LUN-level snapshots. All it would requi= re is proper layout on the storage side. If a LUN (or more LUNs) is dedicat= ed to a VM, then you need to freeze the writes in a VM for a little and cal= l the API of the storage to snapshot the LUN. Removal of a snapshot would b= e fully transparent. Where it gets more complicated is an app-aware snapsho= t. And revert to a snapshot, that would have to be done very carefully, nod= es should not start panicking that they lost storage.
