Server: Debian squeeze
smartmontools 5.39.1+svn3124-2
Hello,
The temperature I get from the log file is very different from the one I get with the smartctl command:
cat /var/log/syslog | grep Celsius
May 7 07:00:19 interne smartd[17990]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 119 to 118 May 7 07:00:19 interne smartd[17990]: Device: /dev/sdc [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 118 to 117 May 7 07:30:18 interne smartd[17990]: Device: /dev/sdc [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 117 to 118 May 7 08:00:18 interne smartd[17990]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 32 to 33 May 7 08:00:19 interne smartd[17990]: Device: /dev/sdc [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 118 to 117 May 7 08:30:19 interne smartd[17990]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 33 to 32 May 7 08:30:20 interne smartd[17990]: Device: /dev/sdd [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 121 to 120 May 7 10:00:20 interne smartd[17990]: Device: /dev/sdc [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 117 to 118 May 7 11:00:19 interne smartd[17990]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 32 to 33 May 7 11:00:19 interne smartd[17990]: Device: /dev/sdd [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 120 to 121 ...
And when I use smartctl:
smartctl -x /dev/sda

(same values for sdb, sdc & sdd)
Any idea where that comes from?

Thanks for your answer.
Sorry to not have seen that in the FAQ.
About the version, it's the version that goes with Debian squeeze.
Debian wheezy became the new stable version 3 days ago and will install v5.41+svn3365-1 (also old, I know, but we like stability on our servers ;))
Thanks again

" directive to suppress these log entries. Add "-W ...
" directive to enable temperature logging (see smartd.conf man page).BTW: Your smartmontools version is more than 3 years old, please update if possible.
