Someone asked a good question about the clone and snap-manager licenses, so I wanted to clarify.
The info I received is that if you use the new snap-manager for ZFSSA product, all snaps and clones created by that product are covered by it's one-time license. You do not need the additional clone license to manage these at all.
However, if you had other clones you are creating that are NOT created via the snap-manager tool, then yes, you do need the other clone license for these to be supported.
I hope that makes sense.
