![smartctl 驱动器 Media_Wearout_Indicator 值超出正常范围](https://linux22.com/image/715789/smartctl%20%E9%A9%B1%E5%8A%A8%E5%99%A8%20Media_Wearout_Indicator%20%E5%80%BC%E8%B6%85%E5%87%BA%E6%AD%A3%E5%B8%B8%E8%8C%83%E5%9B%B4.png)
我试图在生产数据库上设置一些监控来跟踪 SSD RAID 的运行状况。通常,我期望 Media_Wearout_Indicator 的值介于 100(新)和 0(死)之间,但我得到了一些较大的任意值。这是否意味着磁盘仍然处于良好状态?我是否缺少显示值的参数或参数?
