我的服务器正在运行 Cloudlinux，并且有一个软件 RAID 镜像（由 /dev/sda 和 /dev/sdb 组成的 /dev/md2）安装在 /
它一直运行良好，但在模拟 raid 故障并重建镜像后，它不会自行重启。相反，它会将我转至 grub> 提示符。
如果我这样做，它将正常启动：
grub> root (hd0,1)
grub> kernel /boot/vmlinuz-2.6.32-531.29.2.lve1.3.11.10.el6.x86_64 root=/dev/md2
grub> initrd /boot/initramfs-2.6.32-531.29.2.lve1.3.11.10.el6.x86_64.img
grub> boot
但无论我怎么尝试，我都无法让它自动启动。就好像它没有看到 /boot/grub/grub.conf（符号链接到 menu.lst）/boot/grub/grub.conf 看起来像这样：
default=0
timeout=2
title CloudLinux Server (2.6.32-531.29.2.lve1.3.11.10.el6.x86_64)

我已经使用 grub-install 在两个驱动器上重新安装了 grub，并且还完成了以下操作：
grub> find /boot/grub/stage1
(hd0,1)
(hd1,1)
grub> device (hd0) /dev/sda
device (hd0) /dev/sda
grub> root (hd0,1)
root (hd0,1)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0)

Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes

Done.

有任何想法吗？
