我已经让我可靠的QNAP NAS（T869-RU）在RAID5 MDADMarrays中八个磁盘中的两个（显然是）

所有驱动器都报告自己是干净的，尽pipe有些因不健康而被删除，即：

任何想法，我可以在这里做什么？ 假设两个驱动器显然不工作，但是它们也显得干净/健康，所以发生了许多其他事情。
看起来Web界面（显示驱动器运行状况和RAID控制面板）必须由主arrays（/ dev / md0）驱动，因为除了QNAP服务器上的SSH之外，
谢谢
忽视这个问题。
最后与QNAP的支持人员交谈，他们认为sda是一个问题驱动器，另外一个驱动器被标记为不干净，但没有问题。 我目前正在从等待交付两个替代品的8个驱动器中的7个中运行它。
