Following up on what you've mentioned I tried the zbd -S pool

cmd and came up with this:

But understand the pool (tdd) already has dedup turned on as well as
tdd/Images

What do the various SIZE columns mean?  The figure 268G and 262G look
much closer to what I expected.

What is the difference between 'allocated' and 'referenced'?  Looks to
be something like 300G difference
