init_constants_early: too small LEBs?

[Ralf Schlatterbeck]

I'm trying to get an ubifs on a 2MB NOR flash.

I'm following the usual steps for generating everything from inside the 
embedded system:
ubiformat /dev/mtd7
ubiattach /dev/ubi_ctrl -m 7 -d 7
ubimkvol /dev/ubi7 -N testvol -s 1968KiB

But when I try to mount I'm getting:
# mount -t ubifs /dev/ubi7_0 /mnt/
mount: mounting /dev/ubi7_0 on /mnt/ failed: Invalid argument

and the kernel log tells me:
Nov 19 21:07:33 board kernel: UBIFS error (pid 1504):
init_constants_early: too small LEBs (3968 bytes), min. is 15360 bytes

Any advice on what to try next?

Should I use a jffs2 on top of UBI using gluebi or run jffs2 on the
naked md device instead? I'd really like to be bad block tolerant but
don't know if this makes sense with NOR-Flash (of this size) at all.

Thanks
Ralf
