SSD temperature signaling

[Red56]

Just read in system log the following:

May 02 11:29:04 ceto smartd[807]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 108 to 109
May 02 11:59:04 ceto smartd[807]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 109 to 110
May 02 12:15:01 ceto CRON[180081]: pam_unix(cron:session): session opened for user root(uid=0) by (uid=0)
May 02 12:15:01 ceto CRON[180082]: (root) CMD (cd / && run-parts --report /etc/cron.hourly)
May 02 12:15:01 ceto CRON[180081]: pam_unix(cron:session): session closed for user root
May 02 12:29:04 ceto smartd[807]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 110 to 109
May 02 12:59:04 ceto smartd[807]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 109 to 110
May 02 13:15:01 ceto CRON[189561]: pam_unix(cron:session): session opened for user root(uid=0) by (uid=0)

Are these temperatures normal? How do they get that high?

That number is usually not the temperature in dregree celsius. See smartctl -a /dev/sda for proper values. The "Temperature_Celsius" field should show you min/current/max values in degree C.

Thanks, that is a relief really.

 

[Dunuin]

So your "108" number in the logs should translate to 35 degree C.

 

[Red56]

As in RAW_VALUE, right?

 

[Dunuin]

yes
