The zpool version is anachronistic once you have feature flags, so we just
report that.  Alasdair meant to ask, "is your pool at version 28, or using
feature flags".

If you can post the whole output of "zdb -vvv", that would help to debug.
 Also if you are able to reboot the system, you might try that and see if
you are then able to destroy the snapshot.  Wouldn't hurt to take a dump as
you reboot ("reboot -d").
