"zfs list -t all" usually works for me. Look at "USED" and "REFER" My understanding is like this: REFER -> how much data that fs/snapshot refers to, usually the same as (or close to) "df" output for fs. USED -> how much data that fs (including its snapshot) uses, or how much data that particular snapshot uses which is not also in the previous snapshot. You might also be interested in the output of "zfs get usedbysnapshots,usedbydataset,usedbychildren dataset_name" > Is there another tool that helps to visualize disk space usage and references > to data, or could one potentially be made?

The "usedbysnapshots" property shohuld give an idea how much space will be regained if you delete all snapshots. It's somewhat new property (starting zpool v13, I think). -- Fajar _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
