Yeah, I got the same. My first thought was that it's sourced from the storage manager? F4-SSD, these warnings are showing up after a reboot / upgrade and were introduced this and the release before, if I recall well.

The error you encountered is due to the compatibility issue between the system service and the device after the TOS update.

It generally does not affect data security or core functions. We recommend performing a complete system restart. These errors will disappear on their own after the restart.

non-standard boot method

what does that mean
When the developers write the code, tell them to use "standard" methods!

I think the non-standard boot only takes place one time after the update, not every time

This issue is a defect of the current system. We are currently testing this situation and will optimize it in the subsequent version. Thank you very much for your feedback.

Updated successfully on F5-221. Looks like there was a code regression...Disk Hibernation is turned back on again after this update. No other issues at this time.

Updated successfully on F8 SSD Plus. For now no any issues.

re non-standard boot: I took opportunity to do a full shutdown (via GUI) while I moved the device. After restart all seems ok.

Update from 7.0.0448 on my F2-423, The first update attempt reported a download error, even though the internet connection was fine.
The second attempt, after restarting the PC and NAS, initially proceeded normally, but after waiting about 30 minutes, the update failed. All the indicator lights on the NAS were lit normally, but the login page was not displayed.
Attempts to update via the TNAS PC ver. 5.2.520 and a browser (Chrome and Firefox latest version) were unsuccessful, even though the internet connection and firewall were unchanged.





Before anyone says anything weird, here are the results of the internet connection test.



What should I do?

Thank you for your feedback. We are currently testing this issue internally and expect to optimize it in a future version. Thank you for your understanding.
