Interesting, df shows same as zfs:

df -h home

Filesystem            Size  Used Avail Use% Mounted on
data/students/GRAD/ECE/vwb
20G 14G 6.4G 69% /data/students/GRAD/ECE/vwb

So looks like df reports same thing as ZFS does.

Next thing I going to try is to umount the zfs mount and remount to see if that forces it to see the new disk usage.

Here are actual numbers:

As you can see there is about 3Gb difference in what du reports and what
ZFS reports.  I bumped up his quota so that he could work.
It's been days since this was done and ZFS is not change the disk usage.

zfs list -o space data/students/GRAD/ECE/vwb
NAME                        AVAIL   USED  USEDSNAP  USEDDS

data/students/GRAD/ECE/vwb  6.37G  13.6G         0       0 0

Just out of curiosity, have a look at "df -h" to see if it is the thing
reported by "du" or "zfs list". Chance are, it'll be identical to "zfs
list", since it uses the kernel's filesystem info interface, rather than
doing the couting by hand (as "du" does).
