FYI, ZFS v28 is now available in experimental. Among other things it implements triple-parity RAID-Z and Deduplication, Please test if you can. If you want to try, you'll need: - kfreebsd-image-9.0-* - zfsutils (8.3~svn226546-1 or later) Then reboot, "zpool upgrade" and update grub to a recent version (grub-install). ZFS v28 is not supported by older GRUB versions!! DON'T FORGET TO UPDATE GRUB!!! Enjoy :-) -- Robert Millan
