Help me recover my old TrueNAS

I have 1 unused disk to add to my pool.

but, it says Pool contains DEGRADED dataVDEVs

And there is a long list of VDEVs

I’m not sure how to add the unused disk to the pool, or how to address the degradation.

What does

zpool status -v say ?

I’m having problems finding the command prompt

Please use other thread

Have ypu read the user guide? That is a great place to start if you don’t know where to find the command line interface CLI.

Please take a quick read of my linked Joe’s Rules. It is short and to the point on what data we need to help you.
