我在 Linux 上的 AVAGO MegaRAID SAS 9361-8i 上经历了几分钟内一系列奇怪的磁盘“故障”。在此期间，热备用驱动器从未启动。忽略几个不相关的 JBOD 驱动器（看起来没问题），定义的 DG 是 RAID6。当第三个磁盘发生故障时，DG 被脱机。由于磁盘一起发生故障的速度如此之快，我怀疑它们不是真正的问题。我想也许我可以尝试恢复 DG。
我重新启动了设备，现在磁盘被标记为“外部”：

请注意，我不知道为什么它们被标记为“外部”；我没有移动、添加或删除任何磁盘。

当我尝试导入时，它失败并出现错误：

我想也许可以尝试强制预览的离线驱动器联机，但是：

这三种情况都会发生。
有什么方法可以恢复吗？另外，有人听说过这种突然发生的磁盘级联故障，而热空间却在旋转吗？
