<p>前幾天修復了因為intel cpu bug 導致無法使用的 synology DS415+</p>
<p>詳情請看 <a href="https://h.cowbay.org/post/first-try-synology-ha/">https://h.cowbay.org/post/first-try-synology-ha/</a></p>
<p>今天趁尾牙前夕，手邊沒啥要緊事</p>
<p>就來玩玩看promox 加上 synology high availability 再加上 NFS share 的環境</p>
<p>先上架構圖</p>
<p><img src="https://i.imgur.com/k7IDZ4Y.png" alt="" /></p>
<p><img src="https://i.imgur.com/k7IDZ4Y.png" alt=""></p>
<p>架構很簡單，NAS設定一組NFS share， proxmox mount 進來，然後開一台VM在NFS 上</p>
<p>主要來談談proxmox 在碰到synology high availability 切換狀態、遇上腦裂(brain split)時候的狀況</p>
<p>觸發 brain split (說真的，我覺得腦裂很難聽 &hellip;)的情況，在上面連結那篇文章裡面有提到，就不多說了</p>
<p>來講講後續的狀況</p>
<p>發生 brain split 時，可以預期管理者會登入管理界面去修復</p>
<p>關於修復brain split 可以看看群暉的這篇文章</p>
<p><a href="https://www.synology.com/zh-tw/knowledgebase/DSM/help/HighAvailability/split_brain">https://www.synology.com/zh-tw/knowledgebase/DSM/help/HighAvailability/split_brain</a></p>
<p>而我選擇的是 [將兩台伺服器一同保留於叢集中]</p>
<p>在進行修復的過程中，會發現VM這邊會變成 read only</p>
<p>聽起來很合理，畢竟在修復時，所有服務幾乎都是停擺</p>
<p>但是呢，等到修復完成後，VM還是read only ，這就有點奇怪了</p>
<p>有跟群暉客服反應過這個狀況</p>
<p>所以在修復完成之後，在proxmox server 這邊直接對NFS 存取做測試</p>
<p>去下載一個template 是 OK 的，在console 裡面直接在NFS touch file 也是可以的</p>
<p>所以Synology high availability 是有正常發揮作用</p>
<p>而promox 這邊，在synology恢復之後，也可以正常存取NFS ，所以也沒有問題</p>
<p><del>那問題就是在VM裡面了，當發生了某些狀況，讓系統進入read only ，就必須透過reboot 才能解決</del></p>
<p><del>或者是看看這個指令用fsck去檢查filesystem 看看有沒有幫助</del></p>
<pre><code>sudo fsck -Af -M
</code></pre>
<p>UPDATE:</p>
</code></pre><p>UPDATE:</p>
<p>在proxmox 論壇上提出了這個問題，有回覆說要用 NFS Version 4.1</p>
<p>經過測試，在掛載NFS share folder 時，如果有指定 NFS Version 4.1</p>
<p>那在HA Cluster 恢復之後，VM也就跟著恢復正常</p>
<p>不必再重開機了！</p>
<p>所以這問題算是解決了！</p>
