今天我做到了apt-get 更新 && apt-get 升级在Linux Ubuntu 12.04.5 LTS服务器。一切顺利。四个小时后，监控工具提醒我磁盘 I/O 超载。I/O 等待时间已达到 10-40%，系统平均负载在 8 核系统上从 1 上升到 20。网站完全变慢了。看起来磁盘或硬件出了问题，但我不太确定。我应该从哪里开始？任何帮助表示感谢。

答案1
您已经有一段时间没有运行 SMART 自我测试了。请尝试运行smartctl -t long <device>。这应该需要几个小时，您可以在以下位置看到进度smartctl -a：
Self-test execution status: ( 0) The previous self-test routine completed
without error or no self-test has ever
been run.
如果它没有像上次运行那样完成并且没有错误，当驱动器是新的时：

Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed without error 00% 5 -
只需摆脱驱动器即可。
我猜@kasperd 是对的。出现 sata 错误/智能日志错误的驱动器已损坏。
顺便说一句，高负载和驱动器损坏之间的关系来自负载测量的内容。负载是等待执行的进程数。等待驱动器返回数据的进程确实是等待执行的进程。
