Given that I have a machine very simmilar to the next DB machine I have a 
good idea of how many inodes I need.

Will do.

The current machine is using 2056 inodes for 1.2TB.. with 3,539,382 inodes 
free. For the next machine I will use a higher number in newfs until I get 
the number of free Inodes close to 100K. That will give the machine plenty of free inodes. 

Thanks for your feedback.
