我有一台笔记本电脑，配备了该死的西部数据硬盘。我已经使用 SMART 来查看加载/卸载周期 ( smartctl -a|grep Load)。它们增长得太快，接近 300,000 的生命周期限制。
我使用 GNOME Disks 将硬盘驱动器 APM 更改为 254，它们停止增加。这本身并不是一个解决方案：我还必须创建/usr/lib/systemd/system-sleep/harddrive.sh一个解决方案systemctl restart udisks2- 当此驱动器设置丢失时，处理从挂起的恢复。
但几个月后，我注意到驱动器再次发出咔哒声，并且加载/卸载确实在增加。什么地方出了错？
我还去查看了 GNOME Disks。我再也找不到 SMART 数据，也找不到驱动器 APM 设置！发生了什么？！
我在 SELinux 故障排除程序中没有 SELinux 警报。

我针对挂起问题的特定解决方法目前无效。此时恢复时配置未应用：
Feb 23 13:02:55 alan-laptop systemd-sleep[4238]: System resumed.
尽管此时启动了 udisks，但仍然出现这种情况：
Feb 23 13:02:55 alan-laptop udisksd[4357]: udisks daemon version 2.6.2 starting
Feb 23 13:02:55 alan-laptop udisksd[4357]: Acquired the name org.freedesktop.UDisks2 on the system message bus
某些版本的 storaged (udisks) 是应该重新应用简历上的设置，但在我的系统上似乎并非如此。我尝试禁用我的脚本，以防它破坏某些内容，但再次从挂起恢复后，hdparm -B /dev/sda显示128.
答案1
注销并重新启动解决了这两个问题。 SMART 和 APM 出现在 GNOME 磁盘中。重新启用我的恢复脚本后，驱动器 APM 设置在从睡眠状态恢复后重新设置为 254。
肯定有一些状态是通过重新启动而清除的，而重新启动 udisk 并没有清除这些状态。
这种情况第二次发生，我注意到下面的 udev 错误在 udisks 停止工作的地方。
运行sudo udevadm trigger /dev/sda允许 udev 重新扫描磁盘，并使 udisk 再次工作而无需重新启动。udevadm info /dev/sda在触发器显示它缺少 udisks 必须使用的属性之前运行（差异）。
udev 事件超时，因为 udev 正在计算挂起的时间。我已经提交了一份漏洞以及具体细节。
udev 事件在 sda 挂起时触发，因为我添加的用于重新启动 udisks 的钩子也在挂起时运行。它设置设备的 APM 值，这需要打开它（然后关闭它）。每当块设备关闭时都会生成 Udev 更改事件，以便在运行 fdisk 或 mke2fs 等实用程序后重新扫描块设备。
