Need more inodes

   When you grow the file system you get more inodes as well.  It
   appears, from looking at several file systems, that the constant is
   one inode for each 4k disk block in the file system.

I too believe this to be so. 

When the system was released, however, I was told by several sources
in IBM that inodes were dynamically allocated as needed.  This does
not appear to be the case (not according to my tests, at least);
though they do appear to be extended when file systems are extended.
This is a lot better than many *nix implementations, but not nearly as
good as the previous claim.
