Spinning up shortly after each Spinning down

[MullenNG]

I just bought a new ReadyNAS 214 and updated to latest firmware (6.7.5). I setup spin-down (5 minutes, all the time) as I rarely use it (mainly only for storage and back-up purpose). However, I noticed that the disk is running all the time. I checked the log, and found that it always spinning up shortly (5~20 seconds) after spinning down.
Here is the latest log (with disk information, only 1 disk installed)

No app installed (used to install QBitTorrent but uninstalled). SMB, AFP, ReadyDLNA, UPnP, HTTP, HTTPS are enabled (all by default). Saw another thread of the issue caused by IPv6 so IPv6 is disabled but not helpful. The disk is pretty empty at this time (485.8GB used).
 
Any suggestion? Is there any way to debug myself, or should I send the log to someone?

Just want to close this topic as the issue is solved.

I contacted customer service, and instructed by engineer to install 6.8.1-RC1, which version fixed the issue.

If Antivirus is enabled, you might try disabling it and see if that makes a difference.

Does it ever stay spun down for more than a few seconds?

[MullenNG]

No, AntiVirus is not enabled.

No. I enabled spindown since Aug12, 22:19:14, and I checked through the log, Best I could get is 25 seconds (3 times), and usually 15 seconds (278 times), and 5 seconds (234 times).

You haven't said much about your network configuration, can we assume you've isolated the ReadyNAS and 'listened' to it or watched the display? How about pulling the network cable, does it stay spun down - I expect it will?

After upgraded to 6.8.0, the issue is still not solved.

Also noticed this in another log file.

Not sure if this means anything.

[MullenNG]

Tested, no, without network, still can only spin down for 15 seconds

[aks]

Sorry, I don't have a RN214, but it should be easy for someone that does to check if their unit can spin down and stay that way for a while.... this will verify if it's a generic problem or some configuration issue with your setup.
