Dynamically creating the volume based on the size of ubifs image size

[Sibin K C]

I have a requirement to create a new volume (it can be static) based
on the size of the ubifs image (say rootfs.ubifs) which I am going to
write into that volume. The aim is to create the volume with the
minimum possible size required to write 'rootfs.ubifs' to that volume
and boot the device from it.

Can somebody please help me in this regard.

Regards,
Sibin
