3 3ware 97504i -磁盘映射/UUID在重新启动时更改

Question

我有一个3ware 9750-4i与36个驱动器运行(4个在RAID 10，休息个别驱动器，即JBOD)。

当我重新启动时，除了RAID 10数组之外，所有驱动器在重新启动时都会更改它们的UUID(这似乎是随机的，因为我已经重启了几次，每次都是完全不同的UUID)。这使我手动遍历32个驱动器，找出它真正应该被映射到哪里，并重新挂载到那里。

我在网上还没有发现任何与这个问题有关的东西，而且总的来说我对RAID卡很陌生。是不是有什么设置我可能丢失了？或者是因为我的内核造成了这种情况(同样，我对内核也不太了解)

编辑:运行Debian 7.6 64位。

注意，我已经将输出限制在最初的几个驱动器上，因为它们都是相同的。

Answer 1

为了解决这个问题，您可以使用LVM/labels来挂载驱动器，而不是它们的名称。这不是解决原来问题的办法，但我希望这能消除后果。
