Diag attached. It started right after I selected the replacement parity drive and started rebuilding the parity. My Googling so far has lead me to believe that this is an actual hardware error. From the message itself, I am guessing it's an L3 cache error. I had just finished pre-clearing the new drive, a 70+ hours process. I stopped the array, deselected the existing 4TB parity drive and selected the new 18TB drive. At that point I restarted the array and stopped the parity rebuild to power down the server and remove the old parity drive and slot the new one into the front HDD bay. Powered on the server, began the parity rebuild at which point I started getting these MCE errors which FCP notified me about. I don't know what that whole process has to do with L3 errors on my CPU so I'm inclined to think it's just a coincidence but I don't really know. I've been running this hardware for many months trouble free up until now. Thoughts? cortana-diagnostics-20230903-0404.zip
