I don't remeber exactly but I think UBI (without fastmap) doesn't know
the size of the mtd partition.
The scan scan what you give to it.
A way to "grow an UBI device could be to append (before or after)
flash formated with ubi format (with --no-volume-table and the correct
--image-seq= and same other param).
If you give erased flash may be the linux driver will format it.
