I would like to understand why I get the below mails about S.M.A.R.T. of my new NVMe drive.

DMESG

  • I have a 960 Pro and the error count increases every day by 1, similarly as your 970 EVO as I can see. Commented Feb 7, 2023 at 19:21
  • In my case the daily error is 0x2002(Invalid Field in Command: A reserved coded value or an unsupported value in a defined field) Commented Feb 7, 2023 at 19:22

I think it is highly likely this is caused by this bug in smartmontools. Someone participating in this thread wrote about the cause of the messages:

The NVMe specification is not very consistent on how to identify what features the controller supports, so in some cases the driver just has to try it and see if it worked.

The log entries are likely harmless driver initiated admin commands (SqId 0) checking if a particular feature is supported. The SSD doesn't need to log an error entry for such commands as it has no impact on media health (which is what SMART is supposed to care about), but it is allowed to save the error if it wants. I personally find these types of errors to be less than useless.

The bug in smartmontools, i.e. the useless messages, was solved here, and it is not present in the release 7.4 (changelog here – "smartd: No longer issues LOG_CRIT warnings if new entries of NVMe error information log do not indicate device problems."). However, the smartmontools bug report has a followup, and it is not clear to me whether it has been solved yet.
