BUG 现象
我设置了硬盘在 30 分钟后休眠。然而经过测试发现，昨晚硬盘每 60分钟就会自动唤醒，这与所设置的硬盘休眠时间并无关联，看起来就像是配置了一个 60 分钟的周期性任务。
根据群友猜测，可能是smart检测，但是我没有找到设置检测周期的地方，以往在威联通系统上，默认好像是设置的一周检测一次的频率。

经初步排查：
/etc/smartd.conf内：
DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner
查询日志好像又不是smartd造成的：

看来就是飞牛系统级程序把硬盘唤醒的原因了。
目前硬盘休眠是全局设置，建议可以增加每个硬盘的休眠策略，以我的使用来说，ＳＳＤ做系统盘，所有应用、docker数据都挂载在ssd上，ssd没有必要休眠，但是我还有两块机械硬盘做了raid1，在没有应用读写上面的数据的情况下，可以实现机械硬盘上时间休眠，我另外还有一台unraid 5块机械硬盘就是这种休眠策略，一直用下来硬盘可以实现长时间正常休眠。
