<div class="post__content"><p>最近因為一直碰到硬碟故障的問題，算起來那一批同時購買的5X顆 seagate 2T硬碟，已經有一半以上故障返修了….</p>
|
|
|
|
|
|
<p>然後又因為一直沒有添購新的硬碟，只能用這些快過保/已過保的撐著</p>
|
|
|
|
|
|
<p>所以最近不斷的在更換機器內的硬碟，而且還沒有熱插拔！</p>
|
|
|
|
|
|
<p>也導致原本負責處理盤點資產的同事困擾，因為跟手邊的紀錄已經對不起來了</p>
|
|
|
|
|
|
<p>然後就變成要對資產的時候，需要一台一台登入，然後去下不同的指令，取得想要的硬體資訊，超級麻煩的！</p></div>

<p>居然不知為何自己產生了，在我記憶中沒有去執行過那個指令</p>
|

<p>翻了一下 bash_history ，裡面也只有下過哪些指令，沒有紀錄時間，完全沒有參考價值(攤手)</p>
|

|

<p>所以翻了一下網路，至少把這兩台主要跑ansible的機器的log功能補上紀錄所有指令以及時間的部份</p></div>
