The 2 Tbyte limit and 32 bit inodes are totally different things.
The 32 bit inode number issue can be solved internally within
the kernel, until you get to system calls, and a number of system
calls want to make an inode number available to user space. Right
now there is no room in the structures returned from these calls
for 64 bits of inode space.
In order for xfs to function beyond the 2 Tbyte limit, all we need
to do is enable large filesystem support again in XFS. This is a
one character change. In xfs_types.h define XFS_BIG_FILESYSTEMS to
1 instead of zero.
