The used space you see by each snapshot is a uniq usage by that snapshot. If you would remove all anapshots you should re-gain 357G-151G of disk space. It's not an issue with ZFS snapshot it's just that no-one has a better idea how to account for used space by snapshots if multiple of them are pointing to the same data. -- Best regards, Robert Milkowski mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
