저는 SSD를 메인 드라이브로, 대용량 저장을 위한 회전 디스크 2개, 미러링된 단일 vdev(및 그 안에 단일 파티션)를 구성한 Debian 시스템을 가지고 있습니다.
이 디스크는 소음이 꽤 심해서 사용하지 않을 때는 회전 속도를 낮추고 싶습니다. 그러나 zfs 파티션을 마운트할 때는 이 작업을 수행할 수 없으며 어떤 IO가 문제를 일으키는지 또는 이를 중지하는 방법을 파악할 수 없습니다( hdparm -S마운트되지 않은 경우 설정에 따라 회전합니다).
두 디스크 모두에 설정 hdparm -s1 -S1 -B10하고 사용해 보았습니다 . 마운트된 zfs 파티션을 사용하는 (영구) 프로세스가 없으며 다음과 같은 출력을 볼 수 있음을 dstat확인했습니다 .fuser -mdstat -D sda,sdb,nvme0n1 -cdngy --top-bio-adv --top-io-adv
