On Unraid 7.3.1 and 7.3.2, all array drives and parity spin up within minutes of manual or automatic spin-down without observable array I/O. Docker can be disabled and third-party plugins removed with no change. Manual spin-down works. Changing the timeout causes immediate correct spin-down, followed shortly by all drives waking up together. Unraid 7.3.0 previously did not exhibit the issue. Hardware is an LSI 9207-8i using both ports
