zfs code - Aug 2009 - *Almost* empty ZFS filesystem - 14GB?

My ESXi box now uses ZFS filesystems which have been shared over NFS. Spotted
something odd this afternoon - a filesystem which I thought didn''t have
any files in it, weighs in at 14GB. Before I start deleting the empty folders to
see what happens, any ideas what''s happened here?

# zfs list | grep temp
zp/nfs/esx_temp                      14.0G   225G  14.0G  /zp/nfs/esx_temp
# ls -la /zp/nfs/esx_temp
total 20
drwxr-xr-x   5 root     root           5 Aug 13 12:54 .
drwxr-xr-x   7 root     root           7 Aug 13 12:40 ..
drwxr-xr-x   2 root     root           2 Aug 13 12:53 iguana
drwxr-xr-x   2 root     root           2 Aug 13 12:54 meerkat
drwxr-xr-x   2 root     root           2 Aug 16 19:39 panda
# ls -la /zp/nfs/esx_temp/iguana/
total 8
drwxr-xr-x   2 root     root           2 Aug 13 12:53 .
drwxr-xr-x   5 root     root           5 Aug 13 12:54 ..
# ls -la /zp/nfs/esx_temp/meerkat/
total 8
drwxr-xr-x   2 root     root           2 Aug 13 12:54 .
drwxr-xr-x   5 root     root           5 Aug 13 12:54 ..
# ls -la /zp/nfs/esx_temp/panda/

drwxr-xr-x   2 root     root           2 Aug 16 19:39 .

Could there be something super-hidden, which I can''t see here?

Thanks,
Chris

Something I''d just like to add, which I forgot to earlier:

There don''t appear to be any snapshots relating to zp/nfs/esx_temp,
either.

Can you show us both of the following:

zfs list -r zp/nfs/esx_temp

and

du -sh /zp/nfs/esx_temp

benr.

Certainly:

# zfs list -r zp/nfs/esx_temp
NAME              USED  AVAIL  REFER  MOUNTPOINT
zp/nfs/esx_temp  14.0G   225G  14.0G  /zp/nfs/esx_temp
# du -sh /zp/nfs/esx_temp
   8K   /zp/nfs/esx_temp
#

Thanks Ben. If preceding events help at all:
The filesystem contained a 300+ GB VMDK, which was deleted using rm, *after* the
last remaining ZFS snapshot on this filesystem was destroyed.

Just spotted I''ve posted this in ZFS Code rather than ZFS Discuss. Not
having the best evening!! I''ve re-posted in ZFS Discuss. Thanks for the
help so far.
