ubuntu 的 Maas 自訂配置

現在，我對 Maas 有這個問題：

我已經為我的 Ubuntu 16.04 安裝進行了自訂配置（因為我的情況需要不同的分割區和磁碟機配置）。我們的伺服器有多個硬碟，其中兩個專用於系統（通常是最小的兩個）。因此，我為此類配置建立了自訂配置，它使用一些腳本來確定最小的兩個磁碟機。之後我們使用自訂分區，包括軟體突襲創建。到目前為止，一切正常，但在某些情況下，grub-install 安裝失敗。問題是：我需要更改 curtin 中的 grub 配置，以便它可以獲得正確的 grub 安裝設備或完全停用 grub 部分。我的 custom_userdata_ubuntu 現在看起來像這樣：

問題是，在某些情況下，我們有兩個系統硬碟，並且在raid 控制器上啟用了JBOD 安裝失敗，導致grub 嘗試將自身安裝在/dev/sda 上，在這種情況下可能不是系統磁碟，而是jbod 磁碟該核心設定為 sda 並且它是空的。有沒有辦法告訴 maas 從內部將 grub 安裝到另一個磁碟上（或停用安裝 grub，因為我在配置的後面部分有它）？

另外還有關於安裝後 maas 行為的另一個問題，它們是：

  1. 釋放伺服器 Maas 時會將其關閉 - 如何停用此類行為？
  2. 此外，在發布後，Maas 不會更改 PXE 的啟動設備，因此第一次啟動失敗後會導致 PXE 配置不再存在。
  3. 成功部署伺服器 Maas 後，介面部分不顯示伺服器 IP 位址，我們該如何解決這個問題？

答案1

現在，我一直在瀏覽 Maas 程式碼和線上參考，所以我創建了新的配置，也許有人會喜歡它。如何運作： 1. 偵測最小的驅動器，如果我們有兩個大小相同的驅動器，則我們使用/、/usr、/var、/home 的安裝點建立軟體raid 2. 當裝置不是sda/sdb 時，Grub正確安裝自身。

無法如預期運作的是 resolv.conf 配置，我認為它是 dnsmasq 或類似的東西，它會忽略我的網路配置並將 127.0.0.1 放入 resolv.conf 中，但會調查它。也可以更改為example.org 之類的內容此外，我還在此列表中添加了我的配置中的最新命令（儘管我省略了其中一些命令），這為puppet 添加了事實，安裝puppet-agent 並運行它（在puppet 之後）運行還有killall部分 - 它需要釋放chroot環境，否則安裝失敗，導致臨時目錄保持忙碌並且無法卸載）
