You won't be able to expand zpool to the whole disk if it occupies only 
slice of the disk.
(thanks to never coming 'block pointer rewrite' feature in OpenZFS)

You can reformat drive using whole disk install.
There is also manual install procedure if you want to call it other name 
then 'rpool'
if it is now external or secondary drive and you want to use it in the 
same time when booted from main drive that has 'rpool' on it.

I don't remember right but I think that OI installed can not rename 
installing pool to boot from, during install, but can be doen manually.
