really?  I've never run into ANY sort of hardware raid that had any such 
restrictions.  I've not used the 3ware stuff, but I've used lots of LSI 
Logic raid (9260-8i, etc), HP SmartArray stuff (p410, etc), Dell PERC 
stuff, etc etc.

anyways, I'm dealing with a pair of single 3TB (2.78 TiB) drives in a 
mdraid mirror here as the system disk.

um, LVM can't see over 2TB of the drive either, unless its formatted 
GPT, whereupon it can't be used as a boot device on a non-EFI system.
