我不确定这是否是要问的社区，但我想我会试一试：
我们通过rocketraid 2470控制器运行14驱动器RAID10的服务器拒绝组装。我们的目标不一定是恢复工作RAID，而是尽可能多地获取数据。
可能由于组装失败，在关闭服务器时，它会卡在引导循环中。所以我目前正在通过USB运行Ubuntu 16.04.1。我已经确定14个磁盘中有2个有故障，并确定它们是哪个。使用本指南，我已经确定了哪些，并试图在没有它们的情况下重新组装。但是，我一直遇到错误：

这是mdadm --examine调用的输出。

很明显，最后三个驱动器已经过时了。驱动器11和13可能永远不会真正活跃，但由于它们只是raid 1中的伙伴，因此阵列直到现在才受到影响。我希望如果我可以重新组装第12个驱动器，那么我将能够恢复大部分数据。有谁知道我能做些什么呢？我也试过没有“非活动”驱动器，但它仍然没有组装驱动器12.我知道我可以尝试使用--run，但我不确定我是否会以这种方式丢失数据。我也犹豫是否将超级街区归零，因为我一直听说这是最后的选择。
请注意，因为我从USB运行它通常cat /proc/mdstat不会返回数组。另外，我不知道数组的结构（如果我这样做会更容易）。
在此先感谢您的帮助。
