You hit the 2TB partition max size (I assume you mean 2TB and not 2GB).

With LVM you can use physical disks as a PV, e.g /dev/sdb instead of 
/dev/sdb1. If you need to boot from the disk too, then you have to use a 
partition table. With such a small RAID anyway, your easiest option in 
that case is to create one root disk (and a /boot), say 20-30GB, on a 
root vg, then two more partitions with the rest of the space and use 
them as PVs for another vg for data/apps.

You can also put all three partitions into one VG if you prefer that.
