<p>最近要開始測試client安裝 ubuntu 18.04 的 ansible playbook</p>
|
|
|
|
|
|
<p>因為要不斷的修正，所以想到一直有在自己電腦上執行的timeshift這個軟體</p>
|
|
|
|
|
|
<p>可以很簡單快速的備份、恢復系統狀態</p>
|
|
|
|
|
|
<p>可是不知道為什麼，在ubuntu 18.04 上安裝就是會發生錯誤….</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>這兩天在弄兩台Freenas ，準備當作Proxmox 的Storage & Server Backup</p>
|
|
|
|
|
|
<p>因為伺服器的限制，只能接六個SATA，我接了六個2T的硬碟做raid10</p>
|
|
|
|
|
|
<p>然後把Freenas 安裝在隨身碟上</p>
|
|
|
|
|
|
<p>不過會一直出現Smartd failed to start 的錯誤訊息</p>

<p>最近在做一台老機器的P2V</p>
|

|
|
|
|
<p>偏偏user說不能關機，所以我用dd + ssh 做線上移轉</p>
|
|
|
|
|
|
<p>這部份有空再來寫</p>
|
|
|
|
|
|
<p>只是因為原來的設定有用mdadm 做raid1</p>
|
|
|
|
|
|
<p>這部份導致移轉過去proxmox 後，會出現raid degrade 導致無法正常開機</p>

<p>因為工作的關係，現在很多時間都花在VIM的操作上</p>
|
|
|
|
|
|
<p>所以之前花了滿多時間，調整出一個適合自己的VIM環境</p>
|
|
|
|
|
|
<p>原本的作法是把這個設定好的環境，丟到自己建立的gitea 上面</p>
|
|
|
|
|
|
<p>然後每到一台新的機器，就要去clone 下來</p>

<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…</p>
|
|
|
|
|
|
<p>不過主管還是希望能夠先問群暉維修的費用多少</p>

<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>
