i'm not sure if it applies to your situation, but when i FIRST starting using ZFS on freebsd, i noticed a similar error, where a filesystem would be totally empty and still show 14 GB space...it's weird but i remember this because i had quotas set (freebsd didn't have refquotas at the time). We had a user who kept running out of space, but swore he shouldn' be, so we deleted all the files and sure enough, it was empty with 14 gb still showing...the only way i was able to solve it was to destroy the filesystem and create it again...i remember this happening 2 times on freebsd 7.2 which used version 6 of ZFS (a much older version)
I'm not sure if this is a common bug or not but i HAVE seen it.
