GUI possible bug in S.M.A.R.T. temperature selection

Hi, is this a bug in the GUI?

I turned on S.M.A.R.T. temperature monitoring and set the maximum to 50°C:

E-Mail notifications are turned on.

After applying the S.M.A.R.T. settings I received this email:

The following warning/error was logged by the smartd daemon:

Device: /dev/disk/by-id/nvme-WD_BLACK_SN770M_2TB_xxxxx, Temperature 61 Celsius reached critical limit of 55 Celsius (Min/Max ??/61)

Device info:

WD_BLACK SN770M 2TB, S/N:xxxxx, FW:731100WD, NSID:1, 2.00 TB

The message does refer to a 55 Celsius maximum. So it does look like the selection list in the GUI is mismatched.

Hello. As you set the thread to solved immediately, I am not sure if it is still relevant for you.

Anyways:

Please post the content of /etc/smartd.conf.

Do you have configured default values for all devices?

I think so.

Quote from votdev

The configuration is generated according this https://github.com/openmediava…es/etc-smartd_conf.j2#L17

-W DIFF[,INFO[,CRIT]] critical temp is setting from UI + 5 degrees, so this is correct. The UI setting is the INFO value. See https://linux.die.net/man/5/smartd.conf

Thank you for looking up and sharing the insights. But how does this make sense from a user perspective? When I select 50° C in the GUI, then I expect to get a notification when reaching 50° C, not 55. I kindly suggest to adjust openmediavault's way to process the data.

Another issue I encountered on a fresh openmediavault (version 7.6.0-1) this morning:

One drive's temperature on the dashboard is 37° C. I turned on temperature monitoring and set it to 50° C.

openmediavault sent me a mail immediately telling:

Executing smartctl -a shows:

So there seem to be two temp sensors on the drive. openmediavault's dashboard shows the Temperature or sensor 1's value? But smartd daemon watches sensor 2 and throws the alert accordingly?

Thanks

OK, thanks. 37° C is also the more realistic value because the drive was not in real usage the last couple of hours.
