Fragment Size
From my assignment of FreeBSD class, I wanna know the meaning of "fragment size". Because of there no an explanation in the first Google result page so I write this blog for you. ^^
Fragment size is a threshold whether this file will hold full block size allocation or not. If the allocating file size more than fragment size, it will get full block size. If not, it will store in the minimum necessary number of contiguous fragments.
