買了一張 DELL 6/iR 低階的raid 卡
來測試把系統裝在硬體做的RAID上結果沒想到居然不能開機...
<!--more-->
都2019年了 DELL 6/iR 這張卡出了快十年了,不懂為什麼在安裝過程都正常
但是裝完之後,都會發生 " no boot device "的錯誤
測試過 ubuntu 16.04 / 18.04 , Debian 9 都是一樣的問題
翻了很久google發現有人提到要修改一個grub的設定
先裝完系統,然後改用 ubuntu 18.04 Live DVD 開機
然後開啟 terminal
依序執行
```
sudo mount /dev/sdf1 /mnt (RAID磁碟代號不一定是 /dev/sdf 先用fdisk -l 確認)
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
```
chroot 完成之後,再進行下面的修改
```
vi /etc/default/grub
找到
GRUB_CMDLINE_LINUX=""
修改成
GRUB_CMDLINE_LINUX="rootdelay=90"
```
存檔後離開,再更新 grub
```
update-grub
```
然後重新開機,開機時間會比較久一點,但是這樣就可以正常開機了。
還是不懂,這到底是 ubuntu的問題還是raid Controller的問題還是 grub 的問題?

最近在弄一台機器想要把ubuntu 18.04 安裝在software raid上
因為新開的機器大部分都是在proxmox上所以很少碰實體機器了
結果在安裝過程中做raid碰到一些問題來紀錄一下
<!--more-->
要先說明 Ubuntu 提供的ISO類型這會牽涉到後續裝raid
底下這是ubuntu 網頁上的ISO列表
![ubuntu iso list](https://i.imgur.com/32JIHL0.png)
大致上分為 Desktop/live-server 兩種
因為我要裝的是server所以我一開始當然是選live-server
但是用這個ISO開機要設定software raid時會出現警告訊息
提示不可以把所有的分割區都指定給 RAID/LVM ,這樣會沒有地方可以放 /boot
錯誤如圖
![create root on raid error](https://i.imgur.com/uhSpn6w.png)
所以我很「鄉愿」的,那就切一個/boot 給它用,算是暫時解決這問題 XD
但是這樣的作法,總有一天會出事
因為如果這個 /boot 掛了雖然底下的系統有做mirror
但還是不能開機那這樣做raid根本沒有意義啊
所以研究了兩天,發現一個很重要的事情
我根本就抓錯ISO了啊
會這樣想是因為中間有其他task在裝debian9
一開始也是抓live-dvd版本
但是這個版本沒有辦法自訂要安裝哪些套件所以預設安裝完會包含windows manager、office、字型等等
加起來總共5.x G ....
然後我還要手動移除這些套件,這不是脫褲子放屁嗎?
翻了一下google發現是因為ISO的關係要去下載netinst的ISO
才能在安裝過程中自訂套件
從這邊延伸到ubuntu的問題
會不會是我也抓錯ISO了呢
再次google相關訊息果然ubuntu也有類似的netboot ISO
![ubuntu mini iso](https://i.imgur.com/G2ImxhQ.png)
檔案很小只有60M左右趕快下載來安裝
這次果然可以在安裝過程中順利設定software raid並且掛載在 / 根目錄底下進行安裝
## BUT .... 對永遠少不了這個BUT
安裝過程會卡住...
![ubuntu install with mini iso hangs](https://i.imgur.com/FpWsjsO.png)
卡在這邊幾個小時了,都不會動
我在猜可能是mirror site 有問題,所以抓套件抓不到就卡住了?
一直卡著也不是辦法於是又去ubuntu官網看了一下發現有另外一個server的 ISO
這個叫 "Alternative Ubuntu Server installer"
在官網的這個位置
https://www.ubuntu.com/download/alternative-downloads
![Alternative Ubuntu Server Installer](https://i.imgur.com/n0E1ea3.png)
進入後,會有個列表,找到 server amd64 的ISO這個才是正確的
和第一次不同的是,這個沒有"live" ,很重要!
![Ubuntu alternative-downloads](https://i.imgur.com/c4GTujY.png)
用這個ISO開機就可以正常的做出software raid並且指定安裝作業系統也不會有卡住的狀況
做出來的系統磁區大概是這樣
![ubuntu root on software raid](https://i.imgur.com/dyWIH7E.png)
這台VM的硬碟是透過10G網卡連到一個四塊Sandisk 240G SSD 組成的raid0空間
順便看一下速度
![10g nfs storage performance](https://i.imgur.com/V9WwIOC.png)
10G就是快就是爽
爽完之後,還是要確認一下... 首先先執行 sudo dpkg-reconfigure grub-pc
看看是不是兩顆硬碟都有裝 grub ,這樣萬一有一顆硬碟故障,另一顆才能啟動
![dpkg-reconfigure grub-pc](https://i.imgur.com/7xAcCbz.png)
看來因為是在安裝過程中就指定了要把系統裝在raid上所以ubuntu很聰明的也自動把grub裝在兩顆硬碟上了
來試試看拔掉一顆硬碟還能不能正常運作
直接在proxmox 管理界面中detach 一顆硬碟
![detach one of mirror raid](https://i.imgur.com/lLFcdk0.png)
果然報錯誤了
![mirror raid failed](https://i.imgur.com/1SFdVA0.png)
重開機看看,也沒有問題,可以順利開機!
開機過程有看到raid 只剩下一顆在運作的訊息
![mirror raid work with one disk only](https://i.imgur.com/oZNIN4D.png)
再來把硬碟加回去
然後用mdadm 指令加入分割區raid就會開始rebuid了
![mdadm rebuild raid](https://i.imgur.com/3nu2Ij8.png)
所以如果有打算要做software raid來安裝ubuntu 作業系統的一開始就要選對ISO
才不會白忙那麼多時間啊!

<p>最近在重新規劃前人留下的backup爛攤子
各個伺服器統一備份到一台backup storage
想說如果每天能夠看到backup storage的磁碟用量的話
就可以抓出備份空間成長速度、推估需要多大的磁碟空間
找了一些工具,結果發現 durep 這個 ubuntu 內建的工具
基本上可以滿足我的需求</p>

<p>Bookstack 是一套非常好用的線上&rdquo;筆記&rdquo;系統</p>
<p>他用圖書館/書本的概念,讓使用者可以建立自己的&rdquo;圖書館&rdquo;</p>
<p>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
<p>而且支援 Markdown 語法</p>
<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
<p>或者是boostnote(只能在本機)</p>
<p>都或多或少有點小缺點</p>
<p>Bookstack則是沒有這些問題不過就是系統「大」了點&hellip;</p>
<p>不過還好有人做成docker的方式來啟動大大的降低了建置的難度(其實也沒有很難啦只是要裝個PHP、弄個DB而已)</p>

<description>&lt;p&gt;最近在弄一台機器想要把ubuntu 18.04 安裝在software raid上&lt;/p&gt;
&lt;p&gt;因為新開的機器大部分都是在proxmox上所以很少碰實體機器了&lt;/p&gt;
&lt;p&gt;結果在安裝過程中做raid碰到一些問題來紀錄一下&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;</description>

<p>最近在重新規劃前人留下的backup爛攤子
各個伺服器統一備份到一台backup storage
想說如果每天能夠看到backup storage的磁碟用量的話
就可以抓出備份空間成長速度、推估需要多大的磁碟空間
找了一些工具,結果發現 durep 這個 ubuntu 內建的工具
基本上可以滿足我的需求</p>

<p>Bookstack 是一套非常好用的線上&rdquo;筆記&rdquo;系統</p>
<p>他用圖書館/書本的概念,讓使用者可以建立自己的&rdquo;圖書館&rdquo;</p>
<p>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
<p>而且支援 Markdown 語法</p>
<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
<p>或者是boostnote(只能在本機)</p>
<p>都或多或少有點小缺點</p>
<p>Bookstack則是沒有這些問題不過就是系統「大」了點&hellip;</p>
<p>不過還好有人做成docker的方式來啟動大大的降低了建置的難度(其實也沒有很難啦只是要裝個PHP、弄個DB而已)</p>

<guid>https://h.cowbay.org/post/ubuntu-1804-install-root-on-raid/</guid>
<description>&lt;p&gt;最近在弄一台機器想要把ubuntu 18.04 安裝在software raid上&lt;/p&gt;
&lt;p&gt;因為新開的機器大部分都是在proxmox上所以很少碰實體機器了&lt;/p&gt;
&lt;p&gt;結果在安裝過程中做raid碰到一些問題來紀錄一下&lt;/p&gt;

<p>買了一張 DELL 6/iR 低階的raid 卡</p>
<p>來測試把系統裝在硬體做的RAID上結果沒想到居然不能開機&hellip;
</p>
<p>都2019年了 DELL 6/iR 這張卡出了快十年了,不懂為什麼在安裝過程都正常</p>
<p>但是裝完之後,都會發生 &ldquo; no boot device &ldquo;的錯誤</p>
<p>測試過 ubuntu 16.04 / 18.04 , Debian 9 都是一樣的問題</p>
<p>翻了很久google發現有人提到要修改一個grub的設定</p>
<p>先裝完系統,然後改用 ubuntu 18.04 Live DVD 開機</p>
<p>然後開啟 terminal</p>
<p>依序執行</p>
<pre><code>sudo mount /dev/sdf1 /mnt (RAID磁碟代號不一定是 /dev/sdf 先用fdisk -l 確認)
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
</code></pre>
<p>chroot 完成之後,再進行下面的修改</p>
<pre><code>vi /etc/default/grub
找到
GRUB_CMDLINE_LINUX=&quot;&quot;
修改成
GRUB_CMDLINE_LINUX=&quot;rootdelay=90&quot;
</code></pre>
<p>存檔後離開,再更新 grub</p>
<pre><code>update-grub
</code></pre>
<p>然後重新開機,開機時間會比較久一點,但是這樣就可以正常開機了。</p>
<p>還是不懂,這到底是 ubuntu的問題還是raid Controller的問題還是 grub 的問題?</p>

<p>在每個分公司都會有一台伺服器作為KVM Host</p>

<p>另一台作為這邊所謂的 &ldquo;Build Server&rdquo;</p>

<p>最近在弄一台機器想要把ubuntu 18.04 安裝在software raid上</p>
<p>因為新開的機器大部分都是在proxmox上所以很少碰實體機器了</p>
<p>結果在安裝過程中做raid碰到一些問題來紀錄一下</p>
<p></p>
<p>要先說明 Ubuntu 提供的ISO類型這會牽涉到後續裝raid</p>
<p>底下這是ubuntu 網頁上的ISO列表</p>
<p><img src="https://i.imgur.com/32JIHL0.png" alt="ubuntu iso list" /></p>
<p>大致上分為 Desktop/live-server 兩種</p>
<p>因為我要裝的是server所以我一開始當然是選live-server</p>
<p>但是用這個ISO開機要設定software raid時會出現警告訊息</p>
<p>提示不可以把所有的分割區都指定給 RAID/LVM ,這樣會沒有地方可以放 /boot</p>
<p>錯誤如圖</p>
<p><img src="https://i.imgur.com/uhSpn6w.png" alt="create root on raid error" /></p>
<p>所以我很「鄉愿」的,那就切一個/boot 給它用,算是暫時解決這問題 XD</p>
<p>但是這樣的作法,總有一天會出事</p>
<p>因為如果這個 /boot 掛了雖然底下的系統有做mirror</p>
<p>但還是不能開機那這樣做raid根本沒有意義啊</p>
<p>所以研究了兩天,發現一個很重要的事情</p>
<p>我根本就抓錯ISO了啊</p>
<p>會這樣想是因為中間有其他task在裝debian9</p>
<p>一開始也是抓live-dvd版本</p>
<p>但是這個版本沒有辦法自訂要安裝哪些套件所以預設安裝完會包含windows manager、office、字型等等</p>
<p>加起來總共5.x G &hellip;.</p>
<p>然後我還要手動移除這些套件,這不是脫褲子放屁嗎?</p>
<p>翻了一下google發現是因為ISO的關係要去下載netinst的ISO</p>
<p>才能在安裝過程中自訂套件</p>
<p>從這邊延伸到ubuntu的問題</p>
<p>會不會是我也抓錯ISO了呢</p>
<p>再次google相關訊息果然ubuntu也有類似的netboot ISO</p>
<p><img src="https://i.imgur.com/G2ImxhQ.png" alt="ubuntu mini iso" /></p>
<p>檔案很小只有60M左右趕快下載來安裝</p>
<p>這次果然可以在安裝過程中順利設定software raid並且掛載在 / 根目錄底下進行安裝</p>
<h2 id="but-對-永遠少不了這個but">BUT &hellip;. 對永遠少不了這個BUT</h2>
<p>安裝過程會卡住&hellip;</p>
<p><img src="https://i.imgur.com/FpWsjsO.png" alt="ubuntu install with mini iso hangs" /></p>
<p>卡在這邊幾個小時了,都不會動</p>
<p>我在猜可能是mirror site 有問題,所以抓套件抓不到就卡住了?</p>
<p>一直卡著也不是辦法於是又去ubuntu官網看了一下發現有另外一個server的 ISO</p>
<p>這個叫 &ldquo;Alternative Ubuntu Server installer&rdquo;</p>
<p>在官網的這個位置</p>
<p><a href="https://www.ubuntu.com/download/alternative-downloads">https://www.ubuntu.com/download/alternative-downloads</a></p>
<p><img src="https://i.imgur.com/n0E1ea3.png" alt="Alternative Ubuntu Server Installer" /></p>
<p>進入後,會有個列表,找到 server amd64 的ISO這個才是正確的</p>
<p>和第一次不同的是,這個沒有&rdquo;live&rdquo; ,很重要!</p>
<p><img src="https://i.imgur.com/c4GTujY.png" alt="Ubuntu alternative-downloads" /></p>
<p>用這個ISO開機就可以正常的做出software raid並且指定安裝作業系統也不會有卡住的狀況</p>
<p>做出來的系統磁區大概是這樣
<img src="https://i.imgur.com/dyWIH7E.png" alt="ubuntu root on software raid" /></p>
<p>這台VM的硬碟是透過10G網卡連到一個四塊Sandisk 240G SSD 組成的raid0空間</p>
<p>順便看一下速度
<img src="https://i.imgur.com/V9WwIOC.png" alt="10g nfs storage performance" /></p>
<p>10G就是快就是爽</p>
<p>爽完之後,還是要確認一下&hellip; 首先先執行 sudo dpkg-reconfigure grub-pc</p>
<p>看看是不是兩顆硬碟都有裝 grub ,這樣萬一有一顆硬碟故障,另一顆才能啟動</p>
<p><img src="https://i.imgur.com/7xAcCbz.png" alt="dpkg-reconfigure grub-pc" /></p>
<p>看來因為是在安裝過程中就指定了要把系統裝在raid上所以ubuntu很聰明的也自動把grub裝在兩顆硬碟上了</p>
<p>來試試看拔掉一顆硬碟還能不能正常運作</p>
<p>直接在proxmox 管理界面中detach 一顆硬碟</p>
<p><img src="https://i.imgur.com/lLFcdk0.png" alt="detach one of mirror raid" /></p>
<p>果然報錯誤了</p>
<p><img src="https://i.imgur.com/1SFdVA0.png" alt="mirror raid failed" /></p>
<p>重開機看看,也沒有問題,可以順利開機!</p>
<p>開機過程有看到raid 只剩下一顆在運作的訊息</p>
<p><img src="https://i.imgur.com/oZNIN4D.png" alt="mirror raid work with one disk only" /></p>
<p>再來把硬碟加回去</p>
<p>然後用mdadm 指令加入分割區raid就會開始rebuid了</p>
<p><img src="https://i.imgur.com/3nu2Ij8.png" alt="mdadm rebuild raid" /></p>
<p>所以如果有打算要做software raid來安裝ubuntu 作業系統的一開始就要選對ISO</p>
<p>才不會白忙那麼多時間啊!</p>
