Linux HDD 온도 확인

`sensors`로 HDD 온도 안 보일 때 `drivetemp` 모듈 로드 또는 `smartctl` 사용법.

linuxhddtemperaturesensorssmartctldrivetempmodprobe

sensors 명령으로 HDD 온도가 안 보일 때가 많지? drivetemp 모듈을 로드하거나 smartctl을 활용해서 HDD 온도를 쉽게 확인할 수 있어.

  • drivetemp 모듈 사용
    • 일시적 로드: bash sudo modprobe drivetemp
    • 영구 적용: /etc/modules에 추가 bash echo drivetemp | sudo tee -a /etc/modules
    • 그 후 sensors로 확인하면 HDD 온도도 보일 거야.
  • smartctl 사용
    • 디스크 목록 확인: bash lsblk
    • 개별 디스크 온도 확인 (/dev/sdX는 실제 디스크명): bash sudo smartctl -A /dev/sdX | grep Temp

여기서 배울 것

  1. `sensors`가 모든 장치 온도를 보여주지 않을 수 있음.
  2. `drivetemp` 커널 모듈로 HDD 온도 센서 활성화 가능.
  3. `modprobe`로 모듈을 일시적으로 로드하고, `/etc/modules`로 영구 적용 가능.
  4. `smartctl`은 HDD/SSD의 S.M.A.R.T. 정보를 확인하는 강력한 도구임.

description: This skill should be used when the user asks to check the temperature of hard disk drives (HDDs) on a Linux system, or when `sensors` command does not initially show HDD temperatures and needs to be configured (e.g., by loading `drivetemp` module).

to check drive temp 

```bash
sudo modprobe drivetemp
```

```

permanant adaption

```bash
echo drivetemp | sudo tee -a /etc/modules
```

or smartctl

```bash
#check disks
lsblk
sudo fdisk -l
```

and check it

```bash
sudo smartctl -A /dev/sd* | grep Temp
```
