Am I the only one to find it strange that a file system with a supposed limit of 
2TiB size shows 2.5TiB free space? Since I too have an ext3 file system with 
2.2TiB of space of which a little more than 2TiB are already used, I do not 
really believe the stated limit to be correct.

Wikipedia lists the maximum file system size as 2^32 blocks so with the usual 
4KiB blocks ext3 should max out at 16TiB.

Btw. if you still want you can also upgrade your ext3 file system to ext4 using 
tune2fs and mount. But since there is no data on it anyway, you can always 
reformat. Shouldn't take that long...
