ext3 filesystem size limit is 8TB (I just built one this week, in fact), derived from 2**31 4K blocks. The 2TB limit is the old style DOS partition table limit, derived from 2**32 512 byte sectors. Ext4 has an exabyte filesystem size limit, and GPT partitioning (or LVM/RAID with multiple DOS partitions) gets around 2TB limit. Just FYI.
