Maximum Filesystem Size
For Linux 2.4, 2 TB. For Linux 2.6 and beyond, when using 64 bit
addressing in the block devices layer (CONFIG_LBD) and a 64 bit
platform, filesystem size limit increases to 9 million terabytes (or
the device limits). For these later kernels on 32 bit platforms, 16TB
is the current limit even with 64 bit addressing enabled in the block
layer.
