系统是Debian 7.0.2 AMD64
卡是LSI 9261-8i
硬盘是Toshiba DT01ACA300 3T * 12
组的RAID 6
第一次组的时候，创建完阵列，还在后台初始化的时候，我就开始写入数据，当时有出错，阵列直接offline，重启的时候提示RAID卡内存错误。
当时想说应该是还在初始化的时候我就写入数据导致的，所以就没理它，等到初始化完毕后才开始写入数据。
然后2个礼拜前，再次要写入数据的时候，才开始写入没5分钟，阵列又offline了，这次直接联系RAID卡的卖家，让换了一个新卡(一换就是10天.....Orz)
新卡拿来后，读取没问题，写入还是写入没几分钟就offline
用smartctl -a /dev/sda -d sat+megaraid,{device id}
命令进行检测，发现有4个硬盘有错误(刚忘了把日志拷贝出来...现在机器在运行磁盘检测看不到)
把这4个硬盘拿出来用HDD Tune 5.5.0版本检查，只有C7 CRC接口错误(值为200，阀值也是200)
阵列掉线时的日志如下
