Ubuntu raid 服务器上的软件包升级和 grub 设置问题

我有一台在 RAID 系统上运行的远程 Ubuntu 10.10 服务器。出于安全原因，我昨晚进行了软件包升级。在升级过程中，出现了 grub 安装屏幕，并询问我要在哪个分区安装 grub。选项有 sda、sdb、md1 和 md2。我决定将它们安装在 sda 和 sdb 分区上。

我想知道，我做出的决定是否正确？如果机器重新启动，它是否可以安全启动？

您可以在下面找到 fdisk 输出和 fstab 挂载点：

Fstab：

proc /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/md0 none swap sw 0 0
/dev/md1 /boot ext3 defaults 0 0
/dev/md2 / ext3 defaults 0 0

只要您的 raid 位于 sda 和 sdb 中，尤其是 /boot 所在的位置，您重新启动系统就不会有任何问题，而且它会工作，因为您已经采用了 shootgun 方法并在所有磁盘上安装了 grub，而 grub 会自动嗅探您的驱动器以查看 /boot 在哪里。
