Disk Usage Question

[theoracle]

I am a newbie with Opnsense, using it on a Protectli VP2420 for a couple of months.

My box has 16GB of RAM, and a 500GB m.2 drive.  I am slowly learning about Opnsense, and while I have plenty of questions about that, I am OK with my current state. 

My disk usage continues to show 0%, although I have turned on (I believe) a lot of logs.  I am asking if there is a way for me to verify/validate that my m.2 drive is actually being used by Opnsense?  It was visible when I was installing Opnsense, but I can't tell that anything is using it.  I realize this question might be more of a FreeBSD question than Opnsense itself, but I believe that you folks can probably point me obtaining answers.

Thanks for your time.

$sudo camcontrol devlist and we can take it from there.
