Recovering From Multiple Write Failed Disks in a LUN
The procedures for reviving a Dead LUN, differ slightly depending on whether the RAID level is 1 or 5. In all cases, it warns that Unfail should only be used on the LAST drive that was marked as failed, which, if unfailed, would transition the LUN from Dead to Degraded. The remainder of the failed drives should be changed from Failed to Replaced--not Unfailed. To do otherwise is to risk loss of data integrity
总的来说:
1.你现在主要的问题不是Rebuild Failed,是Data Unavailable;这个你必须认识清楚;
2.手工REBUILD到99%,应用能访问证明LOST的部分数据不多.但是关键是阵列现在所处的状态是个很不稳定的状态;如果继续运行下去会有更严重的后果.最好的办法当然是趁现在数据在的时候备份重建.
3.硬盘坏有几种方式;有时候是因为硬盘的读写错误次数超过规定的阀值;
4.磁盘插回去任何一个空位就好了.
5.这个方法不过聊尽人事而已,成功的几率不超过10%.
