zfs discuss - Jul 2010 - Help destroying phantom clone (zfs filesystem)

It looks like I have some leftovers of old clones that I cannot delete:

Clone name is  tank/WinSrv/Latest

I''m trying:

zfs destroy -f -R tank/WinSrv/Latest
cannot unshare ''tank/WinSrv/Latest'': path doesn''t
exist: unshare(1M) failed

Please help me to get rid of this garbage.

Thanks a lot.

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.
