Repeating my previous question in another way... So how do they handle "mv home/joeuser home/moeuser" ? Does that mv delete all snapshots below home/joeuser? To make this work in ZFS, does this require that the mv(1) command only work when the user has snapshot delete privilege? I fear that nothing in this thread is moving the problem closer to RFE status :-( -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance Las Vegas, April 29-30, 2010 http://nexenta-vegas.eventbrite.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
