I've long suspected that you should be able to just use mkfile or "dd if=/dev/zero ..." to create a file that consumes most of the free space then delete that file. Certainly it is not an ideal solution, but seems quite likely to be effective. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
