UBIFS recovery fail

[Jacky Lam]

Dear all,

	I have no idea why my UBIFS suddenly corrupted. But when I try to mount
the UBIFS again, the following error appear:

	UBIFS: recovery needed
	UBIFS error (pid 1057): check_lpt_type: invalid type (15) in LPT node
type 2
	mount: mounting ubi0:fat on /mnt/fat failed: Invalid argument

	Is there any way to recovery or let me clear the volume and mount again?

	Thanks.

BR,
Jacky
