Unraid plugged into a zigbee smart switch controlled by home assistant. The zigbee coordinator is dyeing and for some reason turning off the plug then turning it back on.
Weird. This started a couple days ago and this is like the 3rd parity check to complete I guess I should setup some kind of monitoring to see when unraid goes offline. I'll run the following to see what it comes up with.
Parity check keeps running over and over. It find the same amount of errors but does not correct the errors. SMART data looks good. Diag attached.
