If I remember correctly the max file size was some crazy number like 
9,000,000 MB or someing like that, and the max file system size was like 
double that. But below those limits, we found that the raid driver and 
the LVM stuff topped out at a little over 2 TB. Some guys here at work 
made changes to stretch that  into the double digit TB (not sure what 
the exact number was). With LVM your limited to max Physical extent size 
times the max number of physical extents, which if I remember correctly 
topped out at like 16 TB. I am sure they submitted those changes back to 
the community, but I don't know the state of those projects at the moment.
