ermm...UFS on FreeBSD supports file systems larger than 1TB.  Although  
background fsck's will take a fiscal month to complete...

thus said the manual:
The UFS2 filesystem was introduced in 2003 as a replacement to the  
original UFS and provides 64 bit counters and offsets. This allows for  
files and filesystems to grow to 2^73 bytes (2^64 * 512) in size and  
hopefully be sufficient for quite a long time. UFS2 largely solved the  
storage size limits imposed by the filesystem. Unfortunately, many  
tools and storage mechanisms still use or assume 32 bit values, often  
keeping FreeBSD limited to 2TB.


I'm not sure if obsd has merged the changes kirk et. al. made to the  
new UFS or not so ymmv.
