Right.   Specifically it's the smartctl calls in telegraf (part of GUS.) Alternatively you can comment out the [[inputs.smart]] block in Grafana-Unraid-Stack/telegraf/telegraf.conf to disable them.   Seems for whatever reason (new kernel, new smartctl) these calls are recorded as disk activity which causes the disks to fail unraid's "If inactive for X minutes, spindown" test.
