使用smartctl及raid卡管理软件查看硬盘smart信息可以发现Media_Wearout_Indicator值降为1表明寿命完全耗尽。

所有SSD处理方案
查看SSD smart信息方法1、使用storcli64查看阵列卡下挂载的设备序号
./storcli64 -pdlist -a0 |grep Id |awk {print $3}Device Id: 17
Device Id: 18
......2、根据磁盘Media_Wearout_Indicator值判断是否寿命耗尽
smartctl -a --devicesatmegaraid,17 /dev/sda | grep Media_Wearout_Indicator
smartctl -a --devicesatmegaraid,18 /dev/sdb | grep Media_Wearout_Indicator其中sda,sdb为硬盘所属raid在OS下的盘符3、 固态硬盘的保修期除了会受到使用年限的影响之外还可能会受到能够写入硬盘的最大数据量的影响最大数据量由硬盘的具体生产厂家以及具体型号决定。如果经浪潮公司鉴定硬盘的写入数据量已达到或超过最大限制浪潮公司将不会按照保修政策予以维修和更换”故障根因
