Interesting. We don't have any 2TB partitions, but do have some that  
run about 1.4TB. Our 1.4.2 and 1.4.3rc1 clients report:

: scs@stargate {1/264} $; vos partinfo afs37.ifs.umich.edu
Free space on partition /vicepa: 553916904 K blocks out of total  
1409175748

: scs@kedrigern {1/220} $; vos partinfo afs41.ifs.umich.edu
Free space on partition /vicepa: 1337560904 K blocks out of total  
1337593748

Problem could be 1.5.14, or it could be that you need to get closer  
to 2TB before it bites. Server is linux 2.4, afs 1.4.1rc7 with a few  
patches. Our servers are mostly running 1.4.1.
