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.
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.

You could use LVM. Just create 2TB partitions and use them as physical volumes for a large volume group. Then just create one big logical volume from that volume group.
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.
The idea is to create multiple 2TB partitions.
In one specific case I set up a 4TB System by creating a 1G boot volume and 3.99T system volume. Then I created two 2T partitions on the system volume, formatted them as physical volumes and added them to the main volume group. Then you can create a 4T logical volume if you like.
