You did not enable debugging, as it is asked for here:
http://www.linux-mtd.infradead.org/doc/ubifs.html#L_how_send_bugreport

But I took a look into the code, and the following is error 9:

                if (reserved_pebs > ubi->good_peb_count) {
                        dbg_err("too large reserved_pebs %d, good PEBs %d",
                                reserved_pebs, ubi->good_peb_count);
                        err = 9;
                        goto bad;
                }

This means you created a too large UBI volume in the image,
and your real flash is smaller.

Try to enable UBI debugging, and type dmesg, then you'll see
reserved and real eraseblock numbers. 

같은 에러가 떠서 ubi.ini 의 volsize를 늘려줘서 수정하였다.
