Adding a disk to /storage ?

Hi,

LE 8.2.4

It's probably more a Linux question than a LE question.
I installed LE on a PC, with a 1TB disk. Works fine.
I added another disk of 1TB ; /sda/

Can I use it to kinda "expand" /storage to have more space ?

If someone can point in the direction of a tutorial, something I can start with that'll be greatly appreciated!

Thanks in advance,

Éric
