我最初在 Windows 上使用 RST 设置了 RAID1 阵列（不是作为可启动磁盘）。我最近开始将所有内容移动到 xubuntu，所以我尝试了mdadm我的 xubuntu 分区（双启动）。安装和运行mdadm --assemble --scan工作完美无缺，我能够访问它。
当尝试在 Windows 和 xubuntu 分区上重新安装 xubuntu 时，我遇到了 UEFI 问题。我稍微弄乱了启动文件夹，但让它正常工作（通过删除 xubuntu 分区，然后删除 GRUB）。我想这可能会搞砸一些事情，因为安装 xubuntu （使用 boot/EFI + main/data + swap 分区）后，做同样的事情mdadm不再有效。
看来还是得到了认可。它位于 BIOS 设置中的 RAID 卷列表中，并且mdadm确实看到了它，但它卡在auto-read-only.
$ cat /proc/mdstat
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md126 : active (auto-read-only) raid1 sdc[1] sdd[0]

md127 : inactive sdd[1](S) sdc[0](S)

$ sudo mdadm --examine --scan
ARRAY metadata=imsm UUID=370cc1f2:168a5119:88a48e19:b707194b
ARRAY /dev/md/RAID1 Volume container=370cc1f2:168a5119:88a48e19:b707194b member=0 UUID=5ce770a1:9402cfa0:b05fc6fc:a0c281e1
添加这些行会/etc/mdadm/mdadm.conf产生相同的结果（即使sudo update-initramfs -u在修改后运行mdadm.conf）。我尝试了很多事情，包括重新命名卷以删除空格（我尝试过/dev/md/RAID1_Volume和/dev/md0）并仅ARRAY /dev/md0 UUID=5ce770a1:9402cfa0:b05fc6fc:a0c281e1放入mdadm.conf.
另外，我不确定为什么它要同时创建imsm0 和 RAID1_Volume_0。我假设imsm0只是一个实际体积的容器，但我不确定为什么。我也尝试过使用容器的UUID，但是不起作用。
我有点迷失了！

所以它(auto-read-only)消失了，我的两个驱动器分别出现在我的“设备”列表中，并带有原始名称（“RAID1 卷”）！直到现在，在重新安装 xubuntu 后，我才真正看到它们。
