禁止坏磁盘发送垃圾邮件 dmesg/journalctl

  • 772

是否可以使用命令行禁用磁盘？我收到这样的垃圾邮件：

还没有重新启动，因为我还在使用电脑。它使一切都有点滞后。

    片段中的最后一行dmesg表示写入操作失败。

    你可以试试：

    echo 1 | sudo tee /sys/block/sdd/device/delete

    由于写入缓存，将数据发送到磁盘的应用程序已经“承诺”数据与写入的一样好，内核绝对会努力遵守这一承诺。因此，只要磁盘似乎可用，内核就会继续尝试写入数据。此命令告诉内核准备磁盘以进行热拔出。如果有效，/dev/sdd将消失，并且内核可能会尝试在可能的情况下降低磁盘的旋转速度。

    （如果有人知道如何明确告诉 Linux 内核“我命令你丢失对该磁盘的所有缓存写操作”，请随意写下你自己的答案或将其编辑到这个答案中。）
