TrueNAS Scale 22.12.4 misreporting hard drive temperature (running hotter than the sun...)

[FriedLemons]

Hi all,

I recently upgraded to TrueNAS Scale 22.12.4 and since then my hard drive temperatures reported in the UI have been a little (read: a lot) wrong...

Here is my "Disk health" data:

Luckily no disk temperature related alerts!

If I look at a specific disk (sdc) I can see that before the update it was 31C and after the update it is 193274.97m C (which is hotter than the sun!)

According to the command line the temperature is 36 (assuming I'm reading this right)

# smartctl -a /dev/sdc | grep Temp
194 Temperature_Celsius 0x0022 064 055 000 Old_age Always - 36 (Min/Max 22/45)

All of my disks are behaving similarly so its not a specific brand/type of disk.

I googled around and couldn't find anyone else reporting this, its a fun on!

My system is:

TrueNAS-SCALE-22.12.4
Motherboard: Supermicro X9DRD-7LN4F-JBOD
CPU: 2x Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz 8C/16T
RAM: 64GB various, ECC
SSD: 2x Crucial MX500 250GB
HDD: 2x Toshiba 8TB N300
HDD: 2x Seagate IronWolf 8 TB
I have two ZFS pools, the SSD's are mirrored and the HDD's are in RaidZ2


Let me know if there is anything else useful I can try. It looks to be an issue with Trunas reading/storing/processing the data incorrectly but I'm not sure what I can try.

Known bug will be fixed with a 22.12.4.1 release soon.

Not fixed for me at all.

I'm on TrueNAS-SCALE-22.12.4.2 and one pool shows still "hotter then the sun" temps but not under "Reporting"

There's also an issue in 23.10.0
