Hello,

I'm having an odd issue with one of our servers. I replaced one of the disks because it was bad but the new one keeps giving SMART errors as well.
When doing an short or extended manual test I don't see these errors at all. Could it be cached from the failed drive (which was also sdb)?

Syslog:

Does anyone have an idea?

So I noticed that the error being sent is an old error

You can also use the smartctl utility for further investigation.
The original message about this issue was sent at Wed Jun 24 15:14:57 2020 CEST
Another message will be sent in 24 hours if the problem persists.

The serial number that is mentioned in the e-mail is from the old drive that has been removed already.
Is this somewhere cached or something? Shouldn't it notice the drive is gona?
 
I have a similar issue:
Device: /dev/sda [SAT], Failed SMART usage Attribute: 194 Temperature_Celsius.

Device info:
CT240BX500SSD1, S/N:1933E1940072, WWN:0-000000-000000000, FW:M6CR013, 240 GB

Can someone from the proxmox team please have a look at this and maybe give some tips, how to solve this issue and what it actually means?
 
Hi @Zoker

The best it to post your full smartd output:

Code:
smartctl -a /dev/sda

It could be possible that your SSD/HDD to use a wrong SMART temp threshold.

Hi again ;)


194 Temperature_Celsius 0x0022 055 029 050 Old_age Always In_the_past 45 (Min/Max 22/71)

So in plain words smartd try to say that your SSD, had have (In_the_past) TEMPerature > that Max value(71). Now the TEMPerature is 45 C !!!!
In my own opinnion I think even 45 C is not normal/optimum, maybe your server room is too hot, or the airflow in your server case is not OK?

Another ideea is to get the same info for any another HDD/SSD that you allredy have in that server(to see let say "another oppinion")!


Good luck / Bafta !
 
Same here.

I read few time ago about a related temperature bug in some Crucial disk. I not do the update but if your disk is affected u can update the disk firmware if i remember right.

there is nothing to worry about
it is the temperature on the Fahrenheit scale
for example:
75F = 24C
85F = 30C
115F = 46C
Worry about the SSD when the temperature reaches:
149F - 65C = attention- check cooling
158F - 70C = critical - replace the drive
