我有一个 Debian 系统,其中一个 SSD 作为主驱动器,两个旋转磁盘用于大容量存储,并配置了单个镜像 vdev(以及其中的单个分区)。
这些磁盘噪音很大,所以我希望它们在不使用时降速。但是,当安装 zfs 分区时我无法做到这一点,并且我无法弄清楚是什么 IO 导致了问题或如何停止它(它们hdparm -S
在未安装时确实根据设置旋转)
我已经hdparm -s1 -S1 -B10
在两个磁盘上进行了设置,然后尝试使用dstat
.我已经确认fuser -m
没有(持久)进程正在使用已安装的 zfs 分区,并且可以看到如下输出dstat -D sda,sdb,nvme0n1 -cdngy --top-bio-adv --top-io-adv
