![解释 smartctl,硬盘是否出现故障?](https://linux22.com/image/216121/%E8%A7%A3%E9%87%8A%20smartctl%EF%BC%8C%E7%A1%AC%E7%9B%98%E6%98%AF%E5%90%A6%E5%87%BA%E7%8E%B0%E6%95%85%E9%9A%9C%EF%BC%9F.png)
大约一周前,我注意到我的一个驱动器上的文件系统已损坏。我已经用 fsck 修复了几次,但总是遇到问题。我怀疑这可能是硬件故障。我最近了解了 smartmontools,它利用了某些磁盘的自记录功能。运行后
smartctl -t long -C /dev/sda
然后等待指定的时间,我使用以下命令访问日志
smartctl -a /dev/sda
这是输出。尽管驱动器被列为“通过”,但仍检测到五个错误。大家觉得怎么样?

答案1
SMART 值标准化为 100,越低越差。这些价值观看起来都很健康。特别是,不存在不可纠正的扇区或重新分配的扇区,并且原始读取错误率良好。
所以运行长时间的自检,看看是否出现坏扇区。还可以直接运行badblk
扫描,以防万一。
根据到目前为止的信息,我还开始寻找不同的原因,例如内存故障。获得有关哪些内容已损坏、哪些 fsck 已修复以及是否与硬盘的某个特定扇区或整个地方相关的信息将非常有帮助。
