On some new SSD, smartmontools reports only Airflow_Temperature_Cel instead of Temperature_Celsius.
This causes that the drive temperature is not shown on the main information page.
Tested drive: Samsung SSD 840 EVO 120GB (firmware EXT0BB6Q)
Code reference: system-status/system-status-lib.pl (line 389)
Thanks - this will be fixed in the next Webmin release.
The way it's fixed now show two temperatures for some drives as most common drives report Temperature_Celsius AND Airflow_Temperature_Cel whereas some other Temperature_Celsius OR Airflow_Temperature_Cel
Result example with current fix:
sda: 29℃, sda: 29℃, sdb: 27℃, sdb: 27℃, sdc: 19℃
Another issue about temperature could be that some drive report is:
194 Temperature_Celsius 0x0022 020 073 000 Old_age Always - 20 (Min/Max 18/73)
231 Temperature_Celsius 0x0013 100 100 010 Pre-fail Always - 0
In most cases field #231 is not updated an maybe the result could be zero...
But this never happened to me... so it's just a thought.
Thanks, I didn't know there could be two temperatures - I have submitted another fix to only use the first one.
