我的磁盘已经旋转了好几个月。从 Ubuntu 11.10 开始，一直到 12.04。我不知道如何停止它。我在网上查看了关于 ext4 提交时间、noatime 等的各种建议。我按照他们说的做了，但仍然没有运气。现在就像中国水刑一样……我听到那些磁盘不断旋转，这让我开始发疯。
jdb2/dm-1-8 和 jbd2/db-0-8 通常是 IO 占用最多的用户。但是，我几乎关闭了所有东西，“echo 1 > /proc/sys/vm/block_dump”，并观察了 dmesg。jbd2/dm-1 和 jdb2/dm-0 每 60 秒可靠地刷新一次，但在此期间硬盘仍在继续旋转。dm-1 安装在 /home 上，dm-0 安装在 / 上。
我的设置有点复杂：
我有一个 SSD 用于存放根目录，然后有两个常规驱动器，它们通过软件 RAID 进行镜像，其他 LVM 分区也位于其中。
其上是 LVM 分区。然后，/home 用 ecryptfs 加密。

答案1
根据它们的型号（WDC WD20EARX-00PASB0），您的两个 RAID 磁盘都是“绿色”驱动器，它们因不断地停止和取消停止驱动器头而臭名昭著，不建议用于 RAID 应用程序。
查看 smartctl 的输出或通过图形“磁盘实用程序”查看这些驱动器的 SMART 统计信息。由于它们的省电功能，它们很容易出现非常高的加载/卸载循环计数。
WD 提供了一个名为“WDIDLE”的实用程序：

这将允许您更改此属性并减少或禁用自动头部停车，以帮助您恢复理智。
不幸的是，如上所述，不建议在 RAID 应用程序中使用这些驱动器，因此最好的方法是用合适的驱动器替换它们并在将来避免使用它们。
在 Google 上搜索“绿色驱动器突袭”，你会发现很多人都遇到了这些驱动器的问题。
