Jon, I absolutely back up what you say. Presenting logical volumes less
than 2Tbytes then using LVM to join them back up into larger LVs is the
way to go.
For information, I recently installed a 3ware 9650 card for a customer,
and configured a RAID5 set on some 750Gbyte drives, which came to over
2Tbytes. The customer did not want to use LVM. I found that cfdisk would
successfully partition the drive - the requirement was for a 1.6 Tbyte
partition plus two other smaller partitions.
fdisk failed to understand the partition layout, and gave some very
weird results. So I would advise using cfdisk if you are partitioning
huge drives.
