Hi again!

As u can see in this imagem the usage of my file server is 582GB max.

Here you can see that I have 2 HDDs (sdb and sda)

I've installed the Turnkey Linux in sda

So the problem is I want to create a LVM, so I'd like to use the 2 HDDs like 1 do you understand me?

But sda doesnt show me, as you can see in this photo

And if I try to create a physical volume I can't because don't show the sda disk.

I want help.
