Grow UBI device?

[Wolfgang Denk <wd@denx.de>]

Hi,

I'm looking for a clever way to migrate devices (in the field) from
JFFS2 to UBI/UBIFS.  In the end result, I want to have single UBI
device (which covers the whole NAND chip) with several volumes used
with UBIFS.  Unfortunately I must keep some of the existing data.

It would be nice if I could start with a UBI device that is smaller
than the NAND, so I can keep an existing MTD partition with a JFFS2
file system. After copying the data from JFFS2 to a UBIFS volume, I
would like to free and reuse the space of this JFFS2 partition.

Is there a way to "grow" the existing UBI device so that it now also
covers the rest of the NAND chip?  Or is my only option to create a
second UBI device?

Thanks in advance.

Best regards,

Wolfgang Denk
