Linux kernel >2.6.18 fixed ext3 kernel bugs so ext3 can support >8TB filesystem. The filesystem size is still limited up to 16TB due to 32 bit block numbers (based on 4k default block size). It needs e2fsprogs-1.39 to able to create a fs >8TB. To get >16TB filesystem you either move to ext4(avaible >= 2.6.19) or apply 48bit extents patch though, the later is not in mainline.
