Description Anatoly Borodin 2008-06-09 18:10:05 UTC 
tank/storage/unsorted/TODO contains some snapshots, which contained no data since this filesystem was unchanged for a while. Now some big files were removed (~1.8G), and zfs doesn't show the space occupied by snapshots until the only one snapshot is left. The user can see 5.27G and 3.45G numbers, but cannot see 1.8G number until then.
