今天凌晨三点接到 PVE 的警报邮件说有个 MX500 出现了 C5 警告（待映射的块）。

This message was generated by the smartd daemon running on:

   host name:  pve
   DNS domain: homenetwork.******

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

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

Device info:
CT4000MX500SSD1, S/N:2247E******6E, WWN:5-******-1******d6e, FW:M3CR045, 4.00 TB

For details see host's SYSLOG.

但是我下午回家用 smartctl 看数据的时候，就完全没有任何不正常的值……

跑了一遍 SMART 测试也是没有发现任何问题…… 这是什么奇怪的问题？是否需要返厂这块固态？

@alect 查了，smartmontools 的论坛和 unraid 都说是 mx500 的固件报告的值有问题，属于软件 bug ，不需要管。
