在主机上检测到智能错误(CurrentPendingSector)

Question

Smart每天报告以下错误--我的数据中心服务器SSD之一：

This message was generated by the smartd daemon running on:

   host name:  x
   DNS domain: x

The following warning/error was logged by the smartd daemon:

Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors

Device info:
INTEL SSDSC2BB480G7, S/N:PHDV701605XT480BGN, WWN:5-5cd2e4-14d60bdf9, FW:N2010101, 480 GB

For details see host's SYSLOG.

You can also use the smartctl utility for further investigation.
The original message about this issue was sent at Tue Feb  6 18:43:41 2018 EST
Another message will be sent in 24 hours if the problem persists.

Syslog没有显示任何其他信息。

我在其他地方读到，我需要执行一个扩展的智能测试，然后写入测试结果中指定的扇区，以强制驱动器将其标记为一个坏扇区并重新分配。

我做了一个长时间的测试：

sudo smartctl -t long /dev/sda1

但是sudo smartctl -a /dev/sda1 1的输出表明测试完成时没有出错？

真的有问题吗?如果是的话，如何正确诊断？

Answer 1

只有一个待定扇区不是驱动器的问题。只需忽略它，直到它显著增加。

尽管您可以尝试使用以下说明来修复它(首先备份数据！)：https://github.com/smartmontools/smartmontools/blob/master/www/BadBlockHowTo.txt

此外，您还可以将您的驱动器S.M.A.R.T.报告与S.M.A.R.T.的存储库报告中的其他报告进行比较。

Answer 2

最大的问题是，这个部门是否有你关心的数据，试着读取你的数据文件，看看是否遗漏了什么。

在任何情况下，为了避免重复此错误消息，您将需要覆盖数据，以便让驱动器忽略这一点。如果没有其他用途，那么修整块也应该有效。您可以尝试在文件系统上执行fstrim来清除此操作。

智能长测试对媒体进行随机测试，并不是一个完整的测试，因此即使存在错误，也可能成功，特别是如果这是一个可恢复的排序错误，因为制造商不希望单个挂起的错误导致驱动器RMA。
