zfs discuss - Oct 2007 - ZFS Quota Oddness

I''ve run across an odd issue with ZFS Quota''s.  This is an
snv_43 system with several zones/zfs datasets, but only one effected.  The
dataset shows 10GB used, 12GB refered but when counting the files only has 6.7GB
of data:

zones/ABC        10.8G  26.2G  12.0G  /zones/ABC
zones/ABC at now    14.7M      -  12.0G  -

[xxx:/zones/ABC/.zfs/snapshot/now] root# gdu --max-depth=1 -h .
43k     ./dev
6.7G    ./root
1.5k    ./lu
6.7G    .

I don''t understand what might the cause this disparity.  This is an
older box, snv_43.  Any bugs that might apply, fixed or in progress?

Thanks.

is the pool built out of three-disk raidz1 groups and predates snv_42?

if so, it''s probably some facet of:
