This may not be what you're experiencing, but I recently had a similar
experience.

If you "zdb -d poolname" you'll see a bunch of stuff.  If you grep for a
percent % character, I'm not certain what it means, but I know on my
systems, it is a temporary clone that only exists while a "zfs receive"
incremental is in progress.  If the incremental receive is interrupted, the
% is supposed to go away, but if the receive is interrupted due to system
crash, then of course, it remains, and prevents other things from being
destroyed.

As a reproducible thing:  If you are receiving an incremental zfs send, and
you power cycle the system, one of these things will remain and prevent you
from receiving future incrementals.  The solution is to simply "zfs destroy"
the thing which contains the "%" ... and then the regular incremental works
again.

But you have a different symptom from what I had.  So your problem might be
different too.
