리눅스에서 하드정보(SMART) 보기

하드가 얼마나 오래 썼는지 종종 확인하는데 윈도우에는 CrystalDiskInfo 라는게 있어서 쉽게 볼수 있다.
리눅스도 방법이 있겠지 하는 생각에 검색해봄.

linsoo@ubuntu:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev
tmpfs           787M  9.3M  778M   2% /run
/dev/sda2       451G  5.5G  422G   2% /
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/sda1       511M  3.6M  508M   1% /boot/efi
tmpfs           787M     0  787M   0% /run/user/1000

df -h 치면 현재 설치된 하드 파티션 정보가 나옴.
내 기억이 맞다면 물리적으로 하드가 여러개이면 /dev/sdb, /dev/sdc 이런식으로 나갔던걸로 기억함.
뒤에 숫자는 하나의 물리적하드에서 나뉜 파티션 순서이고.
아무튼 난 한개니깐 /dev/sda

우분투 18.04LTS 에서는 smartctl 파일이 기본적으로 없음.

sudo apt install smartmontools

smartmontools 라고 설치를 해줘야 함

내가 주로 이 정보를 보는건 Power_On_Hours 요거 때문임

하드커널 Odroid HC1은 위와 같은 명령 내리면 알수없는 브릿지라고 하면서 안나오는데…

sudo smartctl -x -d sat /dev/sda 

이렇게 써주면 나온다.
