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....
|
|
|
|
|
|
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
|
|
|
|
|
|
所以最近不斷的在更換機器內的硬碟，而且還沒有熱插拔！
|
|
|
|
|
|
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
|
|
|
|
|
|
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！

幾次之後，終於決定透過ansible來做這件事
|
|
|
|
|
|
一開始的想法很簡單，就用 lshw/dmidecode這些指令去做
|
|
|
|
|
|
可是因為手邊的機器有ubuntu 18.04/16.04/14.04 , Debian 9 , Proxmox (based on debian ) , CentOS , FreeNAS
|
|
|
|
|
|
而有些系統預設沒有 lshw / dmidecode (對，FreeNAS 就是說你)
|
|
|
|
|
|
所以變成要依照系統不同，去下不同的指令，雖然都是ansible在跑，但是看到playbook的內容就很煩啊！
|
|
|
|
|
|
然後就不小心讓我翻到了 inxi 這個指令，根本就是救星啊！
|
|
|
|
|
|
直接來看輸出的範例
|
|
|
|
|
|
|
|
|
|
|
|
有沒有，是不是很優！
|
|
|
|
|
|
而且簡單易懂，還能抓到同事想看的資料，像是廠牌、型號、序號、記憶體類型(DDR2/3/4)
|
|
|
|
|
|
所以馬上捨棄 lshw/dmidecode ，改用 inxi 來跑
|
|
|
|
|
|
ansible role 的內容也很簡單
|
|
|
|
|
|
就偵測完之後，把結果送出給設定好的收件人
|
|
|
|
|
|
只是因為系統不同，大致上要分成 ubuntu/debian/centos 以及 freebsd 兩種
|
|
|
|
|
|
所以同樣的task 要跑兩次，一個要帶sudo 一個不用帶
|
|
|
|
|
|
然後BSD系列的機器，在inventory 裡面要帶入 ansible_ssh_user
|
|
|
|
|
|
就這樣，沒有什麼太困難的
|

ansible 又發揮了一次，另外，感覺這個指令可以用來寫資產管理系統耶...威力強大
|
|
|
|
|
|
而且又不用管作業系統是什麼，反正有執行檔，直接派過去 remote 端就好了！
|
|
|
|
|
|
真是讓我相見恨晚啊！
