Hi Stuart,
I ran various forms of the zdb command to see if I could glean
the metadata accounting stuff but it is beyond my mere mortal
skills.
Maybe someone else can provide the right syntax.

Cindy,
Thanks for the pointer. Until this is resolved, is there some
documentation
available that will let me calculate this by hand? I would like to know
how large
the current 3-4% meta data storage I am observing can potentially grow.
Thanks.

Hi Stuart,
The reason why "used" is larger than the volsize is because we
aren't accounting for metadata, which is covered by this CR:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6429996
6429996 zvols don't reserve enough space for requisite meta data
Metadata is usually only a small percentage.
Sparse-ness is not a factor here. Sparse just means we ignore the
reservation so you can create a zvol bigger than what we'd normally
allow.

What does it mean for the reported value of a zvol volsize to be
less than the product of used and compressratio?
