SOLVED: Replaced cache disk, now it is reporting temp error in smart

[smakovits]

Not sure what is happening. Had what appears to be a failed ssd.  Added ssd as cache formatted xfs, everything was looking ok except this line. 
 

190	Airflow temperature cel	0x0023	081	067	026	Pre-fail	Always	Never	81

If you think "Pre-fail" means an error it doesn't, it's just the attribute type.

But is having high airflow temp a bad thing? Normal temp reading appears more normal at 19.  So it is simply the high value and red on airflow temp that has me worried. However, if normal temp is much lower, maybe the reading is a False positive and can simply be ignored.?

That's correct the actual temp is 100-the attribute raw value, so 100-81=19, some devices have it like that.

thanks.  I will ignore it.  Wish devices reported uniformly to avoid such silly potential panic that my server is suddenly overheating.  meanwhile the other 15 drives appeared normal.  However, in the wake of just losing the cache drive and this being the replacement, it was genuine cause for concern.  I will proceed to ignore the message for now. 

 

This also helps explains the jump in value when I made changes to try and increase cooling.  Before the change it was 70 and after it was 80.  Given the above explanation, I did good, lowered the actual temp from 30 to 20.

 

appreciate the info
