Thanks to many helpful suggestions we have now been able to double the number
of inodes in one of our filesystems. The trick is to decrease the default
block and fragment sizes. In the session shown below we have decreased the
blocksize of partition zd1h from 8192 bytes to 4096 bytes and the fragment
size from 1024 bytes to 512 bytes. This doubled the number of inodes - however
it reduced the disk capacity by 4.75 Mbytes.
