有解嗎

[watermelonyu]

我的vg跨了兩顆disk disk1 and disk2

vg上有兩個lv

lv1 只在disk1上

lv2跨在disk1 and disk2上

當disk2壞掉的時候

1)lv1還能mount 起來嗎,怎mount

2)lv2在disk1上的資料還有辦法救回來嗎

answer 1)



你看一下vgchange的-l和-q n的參數. 然後用lvchange -a y ${lvpath}試著把lvol1帶起來後再mount.



answer 2)

maybe(use dd), 還是要問HP..ccc

vg joey include two disk

/dev/dsk/c8t0d5

/dev/dsk/c8t0d6(bad)整個path 都已經不再了

[watermelonyu]

請問你有實際的範例嗎

因為我已經-q n了,但是在vgchange -a y 的過程還是出現該顆disk 不見

# vgchange -a y -q n -l /dev/joey

vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c8t0d6":

A component of the path of the physical volume does not exist.

Activated volume group

Volume group "/dev/joey" has been successfully changed.

Use vgscan -v to recreate /etc/lvmtab.



# strings /etc/lvmtab

接下來就可以將 /dev/joey/lvol1 mount起來了

但是lvol2我還測不出來可以救回來的方法
