我有一台 3ware 9750-4i，上面有 36 个驱动器在运行（4 个在 RAID 10 中，其余为单独的驱动器，即 JBOD）。
当我重新启动时，除 RAID 10 阵列之外的所有驱动器的 UUID 都会在重新启动时发生变化（这似乎是随机的，因为我重新启动了几次，每次都是完全不同的 UUID）。这导致我手动检查 32 个驱动器，找出它应该在哪里真的进行映射并重新安装在那里。
我在网上找不到任何与此问题相关的内容，而且我对 RAID 卡也不是很熟悉。我是不是漏掉了什么设置？或者可能是我的内核出了问题（再说一次，我对内核也不是很了解）
编辑：运行 Debian 7.6 64 位。
请注意，我将输出限制为前几个驱动器，因为它们都是相同的。

答案1
作为该问题的一个解决方法，您可以使用 LVM/labels 来挂载驱动器，而不是它们的名称。这不是原始问题的解决方案，但我希望这可以消除后果。
