Same as with EXT2.
In theory with 4k block size:
(4096/4)^3 * 4096 = 4 000 GB = 4 TB
(plus a bit more, but that is minor detail)
Your application must use LFS extensions, e.g.
open("filename", O_LARGEFILE, ..)
and your "ulimit -f" must be "unlimited", otherwise
you will encounter 2 GB limit of original ABI.
Another limitation that may come and bite you, is
underlying block device capabilities. Prior to 2.6
kernels any block device can not exceed 1 TB size.
(Or 2 TB, depending...)
