Dennis,

Thanks! The controller I've got (I believe it is a 3Ware 9000 series) - I
think that controller does not allow you to create hardware slices on top
of a RAID'ed disk (volume). But that is a good idea in general. I used that
approach on a couple of HP Proliant servers and that worked.

Boris.
