读取 SMART 数据来确定可能的驱动器故障？

第一次尝试弄清楚这件事。我只是想知道这台服务器上的驱动器是否坏了？编译和运行简单任务时，事情似乎很慢（挂起）。例如，平均负载如此之高（8.00），有时 WA% 也很高，但上面什么都没有运行。

我就是搞不懂。我现在正在编译，但顶部什么都没显示，但我的 WA% 已经达到最大值，编译过程就像是坐在这里什么也不做，然后过了一会儿又恢复了。/困惑

hdparm -t /dev/sda1
/dev/sda1:
 Timing buffered disk reads:   40 MB in  8.24 seconds =   4.86 MB/sec

hdparm -t /dev/sda1
/dev/sda1:
 Timing buffered disk reads:   54 MB in  3.19 seconds =  16.93 MB/sec

hdparm -t /dev/sda1
/dev/sda1:
 Timing buffered disk reads:   66 MB in  3.40 seconds =  19.41 MB/sec

答案1

听起来这可能是硬件问题，但根据 SMART 输出，至少该磁盘似乎没有问题。您可以尝试使用 iotop 查看哪些进程导致了所有 IO。因此，回答这个问题：不，根据目前的信息，这看起来不像是硬盘故障。
