今天我做了apt-get update&&
Linux Ubuntu 12.04.5 LTS服务器上的apt-get升级.一切都很顺利.四个小时后,监控工具提醒我磁盘I / O过载.在8核系统上,I / O等待已达到10-40％,系统平均负载从1上升到20.网站变得非常缓慢.
看起来像磁盘或硬件不好,但我不太确定.我应该去哪里挖？任何帮助赞赏.

解决方法
你有一段时间没有运行SMART自测.尝试运行smartctl -t long< device>.
它应该需要几个小时,你可以看到smartctl -a的进展：
它应该需要几个小时,你可以看到smartctl -a的进展：
Self-test execution status: ( 0) The previous self-test routine completed
without error or no self-test has ever
been run.
如果它没有像上一次运行那样没有完成,那么当驱动器是新的时：
SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 5 -
只是摆脱驱动器.
我的猜测是@kasperd是对的.智能日志中出现sata错误/错误的驱动器已损坏.
顺便说一句.高负载和损坏驱动器之间的关系来自负载测量. load是许多等待执行的进程.等待驱动器返回数据的进程确实正在等待执行.
