I expect "-i" should give more # of inodes, since without it, F2FS relied on relatively small (but enough on smaller capacity) checkpoint blocks to provide them. With the option, it expands checkpoint space to allow more nids which will be used for inodes and file's index blocks. Let us know, if you are in trouble with that option. The mount options would be set by default. If your files are mostly larger than 3.5KB, it'd be better to turn inline_data off. If your directories contain huge number of childrens, it'd be better to turn inline_dentry off and tune sys/fs/dir_level.
