cool, thanks for the pointers... I had a side note to review these in conjunction with ggate. So, is there any logical volume manager that works properly under 6.x or 7, ala LVM2 in Linux? ( I know of vinum, but the way I understand it is is pre-GEOM ).

Contrary to popular belief, Unix is user friendly. It just happens to be very selective about who it decides to make friends with.
