I unfortunately wasn't a good engineer. I didn't keep track of when I did changes, so I don't know if one of those caused this or not. I'm totally accepting this is a PEBCAK error, but I'm at a loss of what to look for next. At some point in the past month my cache said corrupt. Not thinking much about it I stopped the array. reformatted the cache , turned the array back on. formatted the drive and everything looked like it was working moved on with my life. Now my 1Tb NVME drive is just there. I can put files on it via cli. Unraid has labeled it cache. I tried to put system on Cache only to try to move it off the spinning drives but it's not being used. so my everything is super slow.
