How can I get more than 64k inodes on old SCO Unix?

This is an ancient post with no relevance to modern systems.

SCO Xenix and all versions of SCO Unix up to and including 3.2v4.2 use 16-bit unsigned integers for inode numbers, so there is a limit of slightly under 65 536 inodes available per filesystem. If you are running one of these versions, you'll have to make multiple filesystems, each with 64k or less inodes.

OpenServer 5 includes two new filesystems, with 27- and 30-bit inode numbers. These provide approximately 130 million and approximately one billion inodes per filesystem, respectively.
