The Linux operating system filesystem maximum size limit has little to do
with the kernel in use but the type and blocksize of filesystem chosen.

Filesystem                 File Limit     Filesystem Limit
ext2 with 1kB blocksize       16GB               2TB
ext2 with 2KB blocksize      256GB               8TB
ext2 with 4kB blocksize        2TB              16TB
ext2 with 8kB blocksize       64TB              32TB  (*1)
ReiserFS v3.5 (Linux 2.2)      4GB              16TB
ReiserFS v3.6 (Linux 2.4)      1EB              16TB
XFS                            8EB               8EB
JFS with 512B blocksize        8EB             512TB
JFS with 4kB blocksize         8EB               4PB
NFS v2 (client side)           2GB               8EB
NFS v3 (client side)           8EB               8EB

*(1) Systems with 8kB pages like Alpha only

GB (gigabyte) = 10^9  bytes
TB (terabyte) = 10^12 bytes
PB (petabyte) = 10^15 bytes
EB (exabyte)  = 10^18 bytes
