<description><p>前幾天公司的一台 Synology DS 415+ 發生異常</p>
|
|
|
|
|
|
<p>注意到的時候,四顆硬碟燈號都不斷的在閃爍</p>
|
|
|
|
|
|
<p>但是已經無法登入系統</p>
|
|
|
|
|
|
<p>重開機之後更慘,四顆硬碟燈號全部橘燈恆亮</p>
|
|
|
|
|
|
<p>底下的電源藍燈不斷的在閃爍</p>
|
|
|
|
|
|
<p>雖然我一再表示不希望送修了</p>
|
|
|
|
|
|
<p>一來是已經過保,二來是DS415+ 本身就有intel bug,三來是因為對synology的NAS 實在沒有愛&hellip;</p>
|
|
|
|
|
|
<p>不過主管還是希望能夠先問群暉維修的費用多少</p>

<title>[筆記] 用 proxmox & Mellanox SFP 網卡土炮 10G LAB </title>

|
<description><p>想做一個 10G 的 LAB 環境出來已經很久了。</p>
|
|
|
|
|
|
<p>只是礙於10G RJ45的卡太貴了,然後光纖的種類又太複雜</p>
|
|
|
|
|
|
<p>如果直接在淘寶購買,很怕會買錯(什麼LC/FC LC/LC 多模單模 單芯雙芯 SFP/SFP+ 又是什麼光模塊的一大堆規格)</p>
|
|
|
|
|
|
<p>所以一直沒有付諸行動。</p>
|
|
|
|
|
|
<p>硬體的工作很久沒碰了,剛好在蝦皮看到有個賣家在賣 mellanox 的X2網卡,以在台灣的價格來說,算很便宜的 (550)</p>
|
|
|
|
|
|
<p>聊了一下,跟他請教了關於線材、光纖模塊的問題,回答也都很快很到位</p>
|
|
|
|
|
|
<p>就直接下訂了兩張網卡、兩個光纖模塊、一條LC/LC 光纖線</p>
|
|
|
|
|
|
<p>就是到貨有點久,等了兩個禮拜左右,一直到昨天東西才寄到</p>
|
|
|
|
|
|
<p>今天就花了點時間測試一下</p>

<description><p>最近在測試metabase,記得幾個月前就有測試過</p>
|
|
|
|
|
|
<p>但是當時的界面和現在的樣子差很多,看樣子改版還滿勤勞的</p>
|
|
|
|
|
|
<p>所以這次改用docker來建立,根本五分鐘不到就建好了(挖鼻孔)</p>
|
|
|
|
|
|
<p>不過呢,很討厭的是,一進去就發現語系採用的是簡體中文</p>

<description><p>因為工作上的需求,有個資料庫需要開放給不同team的人去存取</p>
|
|
|
|
|
|
<p>雖然都是在同一台機器上的同一個資料庫</p>
|
|
|
|
|
|
<p>但是希望能夠不同team的人用不同的資料庫使用者</p>
|
|
|
|
|
|
<p>這樣萬一出事,會比較好抓兇手??</p>

<description><p>這是發生在一個夜黑風高的寂寥深夜&hellip;.. ( What The FXXX &hellip; )</p>
|
|
|
|
|
|
<p>來到這個環境之後,有一個很詭異的狀況一直困擾著我</p>
|
|
|
|
|
|
<p>在每個分公司,都會有一台伺服器作為KVM Host</p>
|
|
|
|
|
|
<p>上面跑兩台VM,一台作為ansible controller (目前沒作用)</p>
|
|
|
|
|
|
<p>另一台作為這邊所謂的 &ldquo;Build Server&rdquo;</p>
|
|
|
|
|
|
<p>用途包含了DHCP Server / Proxy Server (squid3) / APT Proxy (squid-deb-proxy)</p>
|
|
|
|
|
|
<p>問題就發生在這台 Build Server 上&hellip;</p>

<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></description>

<title>Bookstack Docker</title>

<description><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>

<title>筆記- 啟用群暉NAS (Synology NAS)的SSH Server 透過Publickey 認證免密碼登入</title>

<description><p>公司內有幾台NAS,其中有一台用來放開發人員的postgresql dump file
|
|
|
之前都是主要的開發人員上傳到google drive,分享出來 ,然後其他人去抓回來</p>
|
|
|
|
|
|
<p>這樣子有個問題是,當server要存取這些檔案時,就沒辦法了,除非透過一些 3rd party的軟體
|
|
|
像是這篇</p>
|
|
|
|
|
|
<p><a href="https://www.omgubuntu.co.uk/2017/04/mount-google-drive-ocamlfuse-linux">https://www.omgubuntu.co.uk/2017/04/mount-google-drive-ocamlfuse-linux</a></p>
|
|
|
|
|
|
<p>或者是這篇</p>
|
|
|
|
|
|
<p><a href="https://www.maketecheasier.com/mount-google-drive-ubuntu/">https://www.maketecheasier.com/mount-google-drive-ubuntu/</a></p>
|
|
|
|
|
|
<p>但是手邊的伺服器,原則上除非有必要,不然都沒有開放internet
|
|
|
所以導致明明檔案就在那邊,但是要取得就是很麻煩</p>
|
|
