Ubuntu raid 伺服器上的軟體包升級和 grub 設定問題

Ubuntu raid 伺服器上的軟體包升級和 grub 設定問題

我有遠端 Ubuntu 10.10 伺服器在 raid 系統上運行。出於安全原因，我昨天晚上進行了套餐升級。升級過程中，出現grub安裝介面，詢問我要在哪個分割區安裝grub。選項有 sda、sdb、md1 和 md2。我決定將它們安裝在 sda 和 sdb 分割區上。

我想知道，我做了正確的決定嗎？如果機器重新啟動，它可以安全啟動嗎？

您可以在下面找到 fdisk 輸出和 fstab 掛載點：

只要您的raid 位於sda 和sdb 中，尤其是/boot 中，重新啟動系統就不會有任何問題，並且它會起作用，因為您已經執行了Shotgun 方法並在所有磁碟上安裝了grub，並且grub會自動嗅探您的驅動器以查看 /boot 在哪裡。
