I have about 130k inodes in use which cause a "theoretical minimum"=20 of 508MB disk on filesystems with 4k inode-density, about 1G with 8k inodes (default is 8k, see by newfs(8)) -i bytes Specify the density of inodes in the file system. The default is to create an inode for every (4 * frag-size) bytes of data space. -f frag-size The fragment size of the file system in bytes. It must be a power of two ranging in value between blocksize/8 and blocksize. The default is 2048 bytes.
