That will be space-inefficient, but if space efficiency isn't your biggest problem, then it can be done. An alternative that is worth investigating is delegation of the create filesystem command. If a user wants a specialized file system, then allow them to create the file systems and set properties as needed. -- richard -- Richard Elling rich...@nexenta.com +1-760-896-4422 ZFS and NexentaStor training, Rotterdam, July 13-15, 2010 http://nexenta-rotterdam.eventbrite.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
