ZFS and free space

Apologies if this is a total noobie question, but I am new to ZFS.
My problem is that 1.8 Tb of disk space has mysteriously disappeared
from my file server:

# df -h | grep home
zroot/home            6.0T    6.0T     48G    99%    /usr/home/storage
zroot/usr/home        4.2T    4.2T     48G    99%    /usr/home

du -sh /usr/home/*
715M    /usr/home/julf
4.2T    /usr/home/storage

So where did the 1.8T go? Don't think the ZFS overhead is that big.
And no, there are no deleted files hanging about.
