A data structure view of ZFS is now available:

We've only got one picture up right now (though its a juicy one!),
but let us know what you're interested in seeing, and
we'll try to make that happen.
Well it's a nice picture, thanks! (could you also make a .svg
version available?)
Say, you're the second person to request that. I used OmniGraffle
which is a really nice tool for creating these pictures, but it
doesn't support SVG. Hopefully they will add support, or i may have
to switch to openoffice.
As a zfs-code-illiterate interested bystander, it would be nice if
the various objects were annotated with short descriptions of their
intent. The same goes for the pointers to objects in other layers,
what is the pointer keeping track of, what kind of information
passes between the layers.
Yeah, some of this requires you to understand some of the code (or at
least reference it).
I'd also love to see what happens on the block level when you take
a snapshot. What objects end up pointing to the same things etc.
And if you could make it into a 3d zooming movie with change-by-
change animations that'd be awesome! ;-)
But this is certainly a lot easier to grok than the linear
descriptions in the on-disk format guide. Thanks!
you're welcome.
