Sep 8 17:57:40 NAS4 systemd[1]: /lib/systemd/system/tnas-mntdata.service:8: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed.

There is currently no evidence in the SMART section proving that the hard drives have actually reached extremely high temperatures.
Thanks for flagging this. I understand your concern about a possible false reading from our system. Those values (125°C / 123°C) are far beyond any normal operating range, so I think it's absolutely worth investigating before taking action.

)you have to admit a log that says "Temperature_Celsius changed from 122 to 125" is very misleading then?CursaYang wrote: ↑09 Sep 2026, 16:39There is currently no evidence in the SMART section proving that the hard drives have actually reached extremely high temperatures.
The logs more accurately indicate that the values of SMART Attribute 194 for /dev/sda and /dev/sdb are continuously fluctuating.
To determine the actual temperature, you need to cross-reference the hard drive model and the full output of smartctl -x.
I will try those commands later but wanted to add that Storage Manager shows a much more realistic 25C to 30C.TMroy wrote: ↑09 Sep 2026, 18:04Thanks for flagging this.

Just for clarity: the temperature shown in the logs comes from smartd, which is the standard smartmontools daemon. It doesn’t guess temperature — it reads SMART attribute 194 directly from each drive. So the software is reading the value the drive itself is reporting. That said, this does not always mean the physical temperature is really that high. Sensor misreadings or incorrect raw value decoding by some controllers/bridges can occasionally happen.
To help us rule out a software or system-level issue, could you try the following?
Run smartctl -a /dev/sda | grep -i temperature and smartctl -a /dev/sdb | grep -i temperature to see the raw values. Let me know if they match the 125°C / 123°C in the log.
Sometimes drives are connected through a USB-to-SATA bridge or an HBA that needs a device type parameter. Try smartctl -d sat -a /dev/sda and see if the reading changes.
Cross-check with an independent source: check the NAS BIOS/management interface, or use another tool such as hdparm -H /dev/sda or the drive vendor’s diagnostics utility.
If possible, do a physical check: power the system down, then carefully touch the disk's metal surface — not the circuit board. If it only feels warm, it's likely a sensor/reporting error. If it's painfully hot to the touch, then the temperature is likely real.
Please share the output of those commands and let us know what you find. If it does turn out to be actual heat, I’d strongly recommend keeping the system shut down until cooling is fixed, as the risk of drive failure is very high.
