From my tests with a swapfile (which matches what I remember from real FSen), I think '-T largefile' vs. default frees up around 1.6% of the capacity, so for 9.1T it'd be around 150G which might be worthwhile _iff_ you are sure about what kind of files will go on that FS. FWIW, in a pinch if you run out of Inodes, you can create an image file on that fs, taking just 1 Inode, format that image differently, loop-mount it and put ton's of files inside the image. It'll eat a bit of performance though. And about the average filesize in a dir: Just find out the size (e.g.: du -msx /foo ) and the number of used inodes (e.g.: find /foo -xdev | wc -l [1]) and then just divide: summed_size_in_unit / number_of_files = avg_size_in_unit for FSen, just divide used space by used inodes.
