HDD Spinning up for SMART read every 15 minutes after going to 6.9.1

[tiphae]

Since upgrading to 6.9.1 all of my HDD spin up for a SMART read every 15 min. (some events pasted below), then spin back down. Some older google results led me to setting the disk spin down delay to be longer than the poll time (1 hour delay and 3700 second poll time), but that hasn't helped. Another recent thread [ here ] marked as closed, but I'm not running any of those dockers. I'm hoping for some additional troubleshooting advice.
