我已经阅读过类似的问题，但我的问题似乎讲述了不同的故事，或者那里的答案对我来说不起作用。
- 在主机上检测到 SMART 错误 (CurrentPendingSector)
- 设备：/dev/sda [SAT]，1 个当前无法读取（待处理）的扇区
- 当前待处理部门 SMART 属性
- smartctl 报告当前待处理扇区为 2，但长时间测试未发现任何错误
我从我的服务器收到以下电子邮件/警报：
Smartd 守护进程记录了以下警告/错误：
设备：/dev/sda [SAT]，1 个当前无法读取（待处理）的扇区
设备信息：CT4000MX500SSD1、S/N：2304E6A3D318、WWN：5-00a075-1e6a3d318、FW：M3CR045、4.00 TB
我运行了一些推荐的诊断命令，但它们没有显示任何错误/问题。
Current_Pending_Sector显示 0 并显示Reallocated_Sector_Ct- 长时间测试未显示任何错误
因此我很困惑到底出了什么问题？
