I am currently turning a computer I built a few years ago into a proxmox server. The system has 3x 2 TB hard drives, when I was installing proxmox I gave it 100 GB on one of the hard drives. The plan was to attach one of the additional hard drives to the plex server ( in its previous use it was mainly used to store movies, TV shows, and music), thus far this is proving to be much more difficult than imagined. I have minimal Linux knowledge, and mostly only used VMs on Windows ( this is definitely much more different than I thought it would be). What I have figured out thus far is that it is attached, but proxmox can not access it (at least that is my understanding so far, there is no uuid). Being that I am new to this I am also finding that I don't fully have the knowledge base to properly search for the info I need, any info that might help lead me to the knowledge I seek would be much appreciated.
