更換磁碟機

05/03/2022

以下概述更換叢集中故障磁碟機所需的步驟。

在節點上執行SSH
- 取得使用中磁碟機的清單。
- 取得連結至節點的所有磁碟機清單。
識別可用的磁碟機。
取得磁碟機自訂資源（CR）故障通知。
更換磁碟機。
驗證叢集CR中的磁碟機是否已成功更換及啟用。

步驟

取得叢集詳細資料：

 kubectl describe <cluster_ID> -n

範例：

 kubectl describe adscl -n astrads-system

SSH至節點：
```
 ssh root@<ip_address>
```

列出該節點上的所有作用中磁碟機：

 runc exec -t firetap /sf/packages/netapp-photon/cmd_firestorm.py -c 'disk show'

回應：

 DISK   OWNER        POOL   SERIAL  HOME        DR HOME
 -----  ----------   -----  ------  ---------   -------
 v0.0   fires-9(09)  Pool0  1234   fires-9(09)
 v0.1   fires-9(09)  Pool0  5678   fires-9(09)
 v0.2   fires-9(09)  Pool0  9101   fires-9(09)
 v0.3   fires-9(09)  Pool0  1213   fires-9(09)

列出該節點上的所有磁碟機：

 lsblk -o NAME,SERIAL,SIZE
kubectl describe adscl -n astrads-system

SSH至節點：
```
ssh root@<ip_address>
```

列出該節點上的所有作用中磁碟機：

runc exec -t firetap /sf/packages/netapp-photon/cmd_firestorm.py -c 'disk show'

回應：

 DISK    OWNER        POOL   SERIAL  HOME        DR HOME
 ------  ----------   -----  ------  ---------   -------
 v0.0    fires-9(09)  Pool0  1234   fires-9(09)
 v0.1    fires-9(09)  Pool0  5678   fires-9(09)
 v0.2    fires-9(09)  Pool0  9101   fires-9(09)
 v0.3    fires-9(09)  Pool0  1213   fires-9(09)

列出該節點上的所有磁碟機：
```
- lsblk -o NAME,SERIAL,SIZE
```

建立故障磁碟機CR:

 kubectl get adsfd -n astrads-system

回應：

 NAME                                   AGE
