There is a lower limit to how far you can go.

Using -N 30000 should have got you there.

The last time I messed with it (5+ years ago) the limit was 4MB/inode
and when you gave it an N value lower than that, you got the 4MB/inode
value.

It sounds like the limit is now 8MB/inode as that would give you about
238k inodes on around 2TB...
