我在由 mdadm 创建的 raid1 上运行 LVM 设置。md2 基于 sda6（主分区：次分区 8：6）和 sdb6（8：22）。md2 是分区 9：2。md2 顶部的 VG 有 4 个 LV，即 var、home、usr、tmp。
首先是问题：启动时，设备映射器似乎选择了错误的分区进行映射！启动后立即显示的信息如下
~# dmsetup table

我必须手动“lvchange -an”所有 LV，将 /dev/sdb6 添加回 raid 并重新激活 LV，然后一切正常。但它阻止我自动挂载分区，显然会导致一系列其他问题。
如果一切正常，信息如下

我认为 LVM 出于某种原因只是“占用”了 /dev/sdb6，而这个磁盘在 raid 中却不见了。我尝试了 lvm.conf 中的几乎所有选项，但似乎都没有用。
下面是一些更多信息，例如配置文件。有人知道这里发生了什么以及如何防止这种情况发生吗？
如果您需要任何其他信息，请告诉我
提前致谢！Dominik

答案1
检查/etc/lvm/lvm.conf- 您需要编辑它并调整过滤器配置。
基本上，LVM 会扫描系统中的所有块设备，并在 /dev/mdX 之前找到 /dev/sdX。
如果你编辑 lvm.conf 并添加类似
filter = [ "a/md/", "r/.*/" ]
它将只扫描 /dev/mdX 设备。

似乎 LVM 卷是在 MD 设备之前组装的。您能检查一下它们的启动顺序吗/etc/rc?.d/（假设启动脚本在那里）？
答案4
更新后问题消失了。由于我无法再重现此问题，因此我不得不“关闭”此主题。如果有人也遇到此问题，请不要问我，因为我有一些关于此问题的日志和文档，尽管我不知道如何解决它。
