You would need to do it at the *pool* level, not the filesystem level. And the only way to guarantee that no writes will be done to a pool is to take the pool offline via zpool export. One more reason to stop using hardware storage systems and just let ZFS handle the drives directly. :) -- Freddie Cash fjwc...@gmail.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
