Hmm, there's a bug in the error message the maximum inode ratio is 8MB
(i.e., 8388608).  That's still smaller than the 32MB which you
requested.  I should change the inode ratio to be larger, since there
are filesystems where such a setting might make sense.  Remember,
though, that you can't expand the number of inodes (at least without
resizing the entire filesystem) after you create it, and that
symlinks, device files, FIFO's directories, etc., all take an inode,
so should think carefully setting a particular inode ratio.

For now, if you want a specific number of inodes, you can just specify
it by hand using -N.
