MTD : No Space left on device

Hi All,
I have been facing a strange problem ( At least strange to me).
I want total 10 partitions on a AMD flash. I created those with
the physical map.(~/mtd/maps/nomadik-flash.c)
Detailed Mapping / Partition is shown in the Log.
I made root file system's JFFS2 image from my linux machine and
then i flashed it on the flash device using tftp commands.
Now the boards boots and load root file system as i wished but it
doesn't allow me to create node or mount another mtd block device
on it , it says NO SPACE LEFT ON DEVICE.
So to make this work i changed the image root file system
partition and hence image size to 16 MB which allows me to mount
another device and allows me to write on FLASh but i don't have
same partitions as i want ( I had to give up some of the
partiotions that is necessary)
*Another strange problem i found is that the actual root file
system is only 8.1 MB ,If i try to restrict the size to 10 MB
using mkfs.jffs2 command it creates 16 MB of image, How can i
achive 10 MB image.
./mkfs.jffs2 -l -e 0x20000 --pad=0xA00000 -d RootFS -o RootFs.img
flashed the root file system from
