Something about -your- installation is causing you to run out of inodes.
A 'normal' FFS newfs with all default values would have roughly twice the
number of inodes you show. And, assumig similar size files, would
let the disk fill to over 94% capacity before runnig out of inodes.

but apparently _didn't_, since it discusses the calculation for default
inode counts, and effective average file size.
Those figures do -not- match what you claim is the situation on your
machine.
It would be wise to determine _why_ your system is 'non-standard' in
that respect, before requesting a change in 'standard' behavior.

You need to figure out why YOU have only half the 'normaal' number of
inodes on -your- filesystem.

That sure looks like a 'help me' request.
