由於某台機器有這樣子的需求....所以找到了相關的教學(如下)

http://hi.baidu.com/enjoyunix/blog/item/4f152e3d820dfc0abba167ca.html

但是跟著做之後發現了些問題(默)...(而且機器已經在跑東西了)

3. 告诉GRUB boot sector 位置

#grub

root (hd0,0) <--出現錯誤訊息 Filesystem type is ext2fs, partition type 0x83

setup (hd0)

grub> setup (hd0)_
Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... yes
Checking if "/grub/stage2" exists... yes
Checking if "/grub/e2fs_stage1_5" exists... yes
Running "embed /grub/e2fs_stage1_5 (hd0)"... 15 sectors are embedded.
succeeded
Running "install /grub/stage1 (hd0) (hd0)1+15 p (hd0,0)/grub/stage2 /grub/grub.conf"... succee
ded
Done.



grub> root (hd1,0)
Filesystem type is ext2fs, partition type 0xfdsetup (hd1)

grub> setup (hd1)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd1)"... 15 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd1) (hd1)1+15 p (hd1,0)/boot/grub/stage2 /boot/grub/grub.
conf"... succeeded
Done.

麻煩各位前輩們給點提示 <(_ _)>

你意思是在已有資料的硬碟弄raid? 還是弄raid後開始有資料

才出問題? 沒有完全備份,千萬不要用已有資料HD製作raid

不是硬raid軟raid的問題,資料先備份,才有本錢打掉重練.

因為一旦出問題,通常比較可行的做法就是打掉重練.

我講的打掉,是指parition等級的,不是OS重灌.

然後 無法開機 不過因為GRUB正好記錄了以前的開機設定
所以可以用之前的開機設定開進來

你的md0有一顆是不是沒找到?
Ophelia avatar

應該有md0 md1 兩個 分別掛載hdc1 hdc2
Delia avatar

你每個md原本就只有一個device?

hda1 hda2 hdc1(md1) hdc2 (md2)

你所謂md1,2應該是 md0,1吧 /proc/mdstat 是顯示 md0,1
Victoria avatar

你是準備把 hda1 加入 md0, hda2 加入 md1 嗎?

怎麼一直沒有回答每個md原本有幾個設備的問題?
瞭解
所以md不是開機 / 所在?

他的做法是將ＨＤＡ的東西複製到ＨＤＣ上面(md0 md1）讓md0
去開機　然後在把ＨＤＡ的資料同步後　設定成兩個都可以開機

現在是卡在無法用md0開機

原po可以google一下grub1針對raid的開機設定再試看看.
如果能弄到開機ok,後面比較單純

不過我那時另有Ubuntu10.04開機光碟不能正確設定raid的問
題,改用8.04切分割才搞定,所以是否grub版本問題也不全然.
