Interesting. The system I'm testing on:
FreeBSD icarus.home.lan 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0: Thu Oct 2 03:04:20 PDT 2008 root at icarus.home.lan:/usr/obj/usr/src/sys/PDSMI_PLUS_RELENG_7_amd64 amd64
Can you provide the output from "zfs get all tank tank/test"?
Below are mine.
Note that for the testing, I set the quota on storage/home to 4G, and
did "dd if=/dev/zero of=/home/filler bs=1g count=8". I've since
set the quota back to 16G.
