Hi--
From your pre-promotion output, both fs1-patch and snap1 are
referencing the same 16.4 GB, which makes sense. I don't see how fs1
could be a
clone of fs1-patch because it should be REFER'ing 16.4 GB as well in
your pre-promotion zfs list.
If you snapshot, clone, and promote, then the snapshot-->clone is
promoted to be the origin file system and so is now charged the USED
space, but the post-promotion snapshot space should remain in the
REFER column.
Try it yourself with a test file system, create a 100m file, snapshot,
and clone. Then promote the clone. You will see that the 100MB in REFER
space of the original snapshot becomes 100MB USED space in the newly
promoted clone. The original snapshot remains 100MB in REFER.
If the test snap/clone/promote works then we need to figure out what's
going on in your rgd3/fs* environment. From your output, it almost looks
like the space accounting for snap1 and fs1 are reversed in your post-
promotion zfs list. I don't know why.
I can't reproduce this in the Solaris 10 10/09 release.
Thanks,
Cindy

I tired to line up numbers, it does not work. Sorry for the format.
