소프트레이드일때 /dev/sdb 에 grub 설치하기.

2014-07-21 15:56:42

/dev/sda, /dev/sdb 하드 2개가 소프트레이드 구성되어 있을때,

/dev/sda 하드 고장시 /dev/sdb 하드로 부팅을 해야 합니다.

그럴때 /dev/sdb 에 grub 을 설치하지 않으면 부팅이 되지 않습니다.

grub> find /grub/stage1
find /grub/stage1
(hd0,2)
(hd1,2)

grub>

device (hd0) /dev/sdb
root (hd0,2)
setup (hd0)

fix it and re-run the script `grub-install'.
