Hi TrueNAS folks,
I am new to TrueNAS and have learned a tremendous amount by browsing and searching these forums, as well as stack overflow and the like. I'm hoping someone here can help me out with what is likely a very simple issue.
I would like to have the four drives in my main pool spin down when they are not being used. I have read all the commentary suggesting this is not a good idea and so forth, but I'd still like to explore the possibility. For context, this NAS is set up as an infrequently used data storage repository. I expect that it will be accessed in bursts of activity spread apart by long intervals (e.g. 12 hours of continuous use, but only once a month). As such, I'd prefer it to rest silently with minimal power consumption when it is not needed.
I have done my best to follow the various instructions, but I have noticed the drives frequently spinning back up from standby, even though no clients are connected, no scrubs should be running, etc.
My configuration is as follows: 4x Seagate Ironwolf HDDs, Supermicro X10, Xeon E3 V3, 16GB ECC RAM, WD SSD for boot
These are the steps I have tried:
The result of my efforts is that the drives do spin down, but I also noticed them running when I hadn't accessed the share at all in days. I logged in to the UI and checked in the shell using camcontrol cmd with mixed results. Sometimes the drives were spinning and sometimes they were in standby. I also ran a quick SMART report (smartctl -a /dev/ada3) and found that the drive has recorded 442 start_stop_count events, almost all of which have occurred in the couple of days since I implemented the power saving settings. Under these circumstances, I've reverted all the settings and will leave the drives spinning for now.
If someone could point me in the right direction, I'd be interested to understand how to configure these options correctly, and if there is some log file that might help understand what is triggering the standby and wake events.
Thanks!

These are the steps I have tried:
- Under Storage > Disks (for all disks in pool)
- Set disk power management level to less than 128
- Check Force HDD Standby
- Set HDD Standby to 60 minutes
- Leave other settings default (SMART enabled)
- System Dataset moved to Boot Pool
- Services
- SMART Check Interval 720
- Other services running are SMB, AFP, UPS and SSH
- Tasks
- SMART Long Test monthly
- Pool scrub default frequency (35 days)
