> My understanding is that even XFS has a maximum filesystem size of only 16TB on 32 bit, even though it goes to 9 EB on 64 bit systems.
Though xfs is fully 64-bit capable on 32-bit machines, the 16T limit is OS-imposed. There is a 32-bit index into the (4k) page cache on x86, so 2^32 * 4096 is 16T is the maximum offset that can be addressed.
