질문을 참고해서여기, 나도 이 블로그에 설명된 대로 모든 속성을 가져오려고 노력하고 있습니다.여기.
저는 Debian 6을 OS로 사용하고 있으며 apt-get을 사용하여 smartmontools 버전 6.3을 설치했습니다. 내 6개 디스크가 RAID에 있습니다. 먼저 명령을 사용하여 통계를 활성화했습니다.
sudo smartctl -s on -o on -S on -d megaraid,0 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,1 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,2 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,3 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,4 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,5 /dev/sda
완료되면 다음 명령을 사용하여 모든 속성을 가져옵니다.
smartctl -a -i -d megaraid,0 /dev/sda
하지만 블로그 기사에서 설명한 대로 어떤 속성도 표시되지 않습니다.
bash-4.1# smartctl -a -i -d megaraid,0 /dev/sda
smartctl 6.3 2014-07-26 r3976 [x86_64-linux-2.6.32-5-amd64] (local build)

내가 여기서 무엇을 놓치고 있는지 단서가 있습니까? SMART 지표를 어떻게 얻나요?
답변1
RAID 어레이에서는 SMART 정보를 추출할 수 없습니다. 어레이에는 이를 가능하게 하는 드라이브인 SMART 정보가 있습니다.
Dev sda는 유닛(sd0, sd1/sda1, sdb1 등)이 아닌 RAID입니다. 따라서 어레이가 아닌 디스크 장치에서 정보를 추출하십시오.
