早些时候我用一种帮助解决了这个问题:) 在Debian上的软件RAID 1 – GRUB光标闪烁
我可以看到菜单，可以再次进入我的XP。 但是，我收到了Debian的错误。
这是selectDebian后发生的事情（从屏幕上，字面上…）
Booting 'Debian GNU........ 2.6.26-2-686' root (hd0,6) Filesystem type is reiserfs, partition type 0xfd kernel /vmlinuz-2.6.26-2.686 root=/dev/mapper/acm_main-root ro quiet [Linux-bzImage, setup=0x3000, size=0x16ce500] initrd /initrd.img-2.6.26-2.686 [Linux-initrd @ 0x,....... meaningless here] Decompressing Linux....

Dropping to a shell! 这是否表示出现了问题？ 我应该重新安装吗？
我尝试了救援CD，并使用vgscan -v，我只发现了acm_tmp，而不是acm_main。 我有两个卷组：acm_tmp和acm_main，其中main具有逻辑组：/，/ home，/ usr，/ var和tmp具有/ tmp。 交换在外面
谢谢。
编辑的 pvdisplay

I will stop here ---Physical Volume --- PV Name: /dev/sdb9 VG Name: acm_tmp .... and the rest are pretty much the same except of course different UUID...
我翻了一番。 这就是我从屏幕上得到的一切。
您是否在RAID设备上创build了卷组？
我怎么知道我做的？ 对不起。 我其实跟着那个video 这似乎是http://www.youtube.com/watch?v=rMyfljiCz3A
fdisk -l（我会跳过开始，结束和块）
Disk /dev/sdb: 500.1 GB 255 heads, 63 sectors/track, 60801 cylinders Device Boot ..skip.. Id System /dev/sdb1 * 7 HPFS/NTFS /dev/sdb2 f W95 Ext'd (LBA) /dev/sdb5 7 HPFS/NTFS /dev/sdb6 7 HPFS/NTFS /dev/sdb7 * fd Linux raid autodetect /dev/sdb8 82 Linux swap / Solaris /dev/sdb9 8e Linux LVM /dev/sdb10 fd Linux raid autodetect
另外，我们上次解决的问题….我有分区号为6的reiserfs，分区types0xfd它看起来非常符合上述
possible partitions are partition num: 0, Filesystem type unknown, type 0x7 num 4: same as num0 num 5: same as num0 num 6: reiserfs num 7: filesystem unknown, type 0x82 num 8: type 0x8e num 9: 0xfd
我想我明白了问题所在。 看起来你的acm_root卷组位于第二个RAIDarrays，由于这个错误，启动有问题：
madam: /dev/md0 has been started with 2 drives. madam: WARNING /dev/sdb10 and /dev/sda10 appear to have similar superblocks. - if they are really different, please --zero the superblock on one - if they are the same, or overlap,\please remove one from the DEVICE list in mdadm.conf.
要解决这个问题，请再次启动到救援模式，然后运行以下命令（如所示）：
mdadm --zero-superblock /dev/sda10
然后再次尝试启动。 希望这可以帮助。
