ubuntu – 不频繁的输入/输出错误 – Linux服务器

偶尔,我们会在其中一个磁盘上遇到输入/输出错误.

我们的服务器(DELL PowerEdge R720,Ubuntu 14.04)使用Perc H710 Raid控制器,产生错误的磁盘是Dell 600GB SAS 6Gbps 15k 3.5″磁盘.

我们总是可以使用fsck.ext4来修复错误,但我们不知道是什么原因导致它们发生.

我们已将服务器固件更新到最新版本,并运行了我们能想到的所有测试.

我们还能做些什么来找到问题的根源？

编辑：

大约一个星期前我们联系了DELL,在他们指示我如何进行多次测试之后,他们得出结论,服务器很好,并且在测试中没有出现任何异常情况.

我无法为设备启用SMART支持：

$sudo smartctl -a /dev/sda

此外,我不知道该怎么做(谷歌搜索没有帮助)：

$sudo hdparm -I /dev/sda

欢迎任何建议！

你有一个驱动器在一个行为不端的RAID,并产生偶尔的错误？听起来像硬件问题,而且可能会变得更糟.您应该考虑更换驱动器.是的,这是昂贵的,但你的时间价值多少,如果整个驱动器在不合适的时刻向南走,会有多糟糕？
