All it means is you can't boot from a partition larger than 2T.
Partition the system in a sane manner and it isn't an issue.

It is a boot loader and fdisk issue.  You can't use fdisk, you have to
use parted to make really huge partitions.  BUT most of the system's
I've seen with that kind of disk space have a system volume [a whole
heck of a lot smaller than 2T] and a data volume.  If you don't want to
bother partitioning data-drives you can add 'raw' drives as pvs to a vg.
Otherwise it is easier to just create 1T pvs and add each of them to the
vg.
