[长期]群晖硬盘噪音改善探讨

目前 8 盘位机箱放了 6 块炒豆子盘，这 6 块盘没有划分成同一个存储池,这是背景。

群晖的根目录会挂载到/dev/md0这个文件系统上， 而这个/dev/md0文件系统是所有硬盘的第一个分区做了 raid1 所生成的逻辑设备。

那么现状是系统组件有日志输出或者其他文件活动就会导致所有硬盘跟着一起哐当哐当（所有硬盘等一起闪），我想做的事是做一些系统设置来环节群晖硬盘噪音。

目前做了把 /var/log 挂载到 tmpfs 上，但是没啥改善还是三秒一次哐当哐当。

各位巨佬能够指点下，作何做进一步改善的思路？ Let's make it!

###开机挂载 tmpfs 到 /var/log 这部分代码放到任务计划里面 root 开机启动执行计划 if [ ! -d "/var/logbak" ]; then mkdir /var/logbak cp -a -f /var/log/. /var/logbak/ fi cp -a -f /var/logbak/. /tmp/log/ mount -B /tmp/log /var/log ###/var/log 已挂载到 tmpfs ，但是噪音没啥改善 alex@nas4alexsu:/var/log$ pwd /var/log alex@nas4alexsu:/var/log$ df -h .
