針對GCP後端設定CVS

貢獻者

瞭Cloud Volumes Service 解如何使用所提供的範例組態、將NetApp for Google Cloud Platform（GCP）設定為Astra Trident安裝的後端。

註 適用於Google Cloud的NetApp Cloud Volumes Service 支援的CVS效能磁碟區大小不得低於100 GiB、或CVS磁碟區大小不得低於300 GiB。如果所要求的磁碟區小於最小大小、Astra Trident會自動建立最小大小的磁碟區。
您需要的產品

以設定及使用 "適用於 Google Cloud Cloud Volumes Service" 後端、您需要下列項目：

  • 使用NetApp CVS設定的Google Cloud帳戶

  • Google Cloud帳戶的專案編號

  • Google Cloud服務帳戶 netappcloudvolumes.admin 角色

  • CVS服務帳戶的API金鑰檔

Astra Trident現在支援預設的較小磁碟區 "服務類型"： [GCP^] 上的 CVS 服務類型。用於建立的後端 storageClass=software、現在、磁碟區的資源配置大小最小可達300 GiB。CVS目前在「管制可用度」下提供此功能、並不提供技術支援。使用者必須註冊才能存取低於1TiB的磁碟區 "請按這裡"。NetApp建議客戶使用低於1TiB的磁碟區來處理*非正式作業*的工作負載。

註 使用預設的CVS服務類型部署後端 (storageClass=software）、使用者必須取得GCP上有關專案編號和專案ID的子1TiB Volume功能存取權。這是Astra Trident配置子1TiB磁碟區所需的功能。如果沒有、則低於600 GiB的PVCS將無法建立Volume。使用取得對低於1TiB磁碟區的存取權 "這份表格"。

由Astra Trident針對預設CVS服務層級所建立的磁碟區、將會配置如下：

  • 小於300 GiB的PVCS會導致Astra Trident建立300 GiB CVS Volume。

  • 介於300 GiB到600 GiB之間的PVCS會導致Astra Trident建立一個所需大小的CVS Volume。

  • 介於600 GiB和1 TiB之間的PVCS會導致Astra Trident建立1TiB CVS Volume。

  • 大於1 TiB的PVCS會導致Astra Trident建立所需大小的CVS Volume。

後端組態選項

如需後端組態選項、請參閱下表：

參數 說明 預設

version

永遠為1

storageDriverName

儲存驅動程式名稱

「GCP-CVS」

backendName

自訂名稱或儲存後端

驅動程式名稱+「_」+ API金鑰的一部分

storageClass

儲存類型：任您選擇 hardware （效能最佳化）或 software （CVS服務類型）

projectNumber

Google Cloud帳戶專案編號。此值可在Google Cloud入口網站的首頁找到。

apiRegion

CVS帳戶區域。這是後端配置磁碟區的區域。

apiKey

的Google Cloud服務帳戶API金鑰 netappcloudvolumes.admin 角色：其中包含Google Cloud服務帳戶私密金鑰檔案（逐字複製到後端組態檔）的JSON-格式內容。

proxyURL

Proxy URL（如果需要代理伺服器才能連線至CVS帳戶）。Proxy伺服器可以是HTTP Proxy或HTTPS Proxy。對於HTTPS Proxy、會跳過憑證驗證、以允許在Proxy伺服器中使用自我簽署的憑證。不支援已啟用驗證的Proxy伺服器。

nfsMountOptions

精細控制NFS掛載選項。

"nfsves=3"

limitVolumeSize

如果要求的磁碟區大小高於此值、則資源配置失敗

""（預設不強制執行）

serviceLevel

新磁碟區的CVS服務層級。這些值包括「標準」、「高級」和「極端」。

"標準"

network

用於CVS磁碟區的GCP網路

「預設」

debugTraceFlags

疑難排解時要使用的偵錯旗標。範例： \{"api":false, "method":true}。除非您正在進行疑難排解並需要詳細的記錄傾印、否則請勿使用此功能。

null

如果使用共享的VPC網路、兩者都是 projectNumber 和 hostProjectNumber 必須指定。在這種情況下、 projectNumber 是服務專案、以及 hostProjectNumber 是主機專案。

。 apiRegion 代表Astra Trident建立CVS磁碟區的GCP區域。Astra Trident可在屬於同一個GCP區域的Kubernetes節點上掛載及附加磁碟區。建立後端時、務必確保 apiRegion 符合Kubernetes節點部署的區域。建立跨區域Kubernetes叢集時、會在指定的中建立CVS磁碟區 apiRegion 只能用於排程在相同GCP區域的節點上的工作負載。

註 storageClass 是選用參數、可用來選取所需的參數 "CVS服務類型"。您可以從基礎CVS服務類型中進行選擇 (storageClass=software）或CVS效能服務類型 (storageClass=hardware）、這是Trident預設使用的功能。請務必指定 apiRegion 提供各自的CVS storageClass 在後端定義中。
重要 Astra Trident與Google Cloud上的基礎CVS服務類型整合、是一項*測試版功能、不適用於正式作業工作負載。Trident 完全支援 CVS效能服務類型、並依預設使用。

每個後端都會在單一Google Cloud區域中配置磁碟區。若要在其他區域建立磁碟區、您可以定義其他後端。

您可以在組態檔的特殊區段中指定下列選項、以控制預設的每個Volume佈建方式。請參閱下列組態範例。

參數 說明 預設

exportRule

新磁碟區的匯出規則

「0.00.0.0/0」

snapshotDir

存取 .snapshot 目錄

"假"

snapshotReserve

保留給快照的磁碟區百分比

""（接受CVS預設值為0）

size

新磁碟區的大小

「100Gi」

。 exportRule 值必須是以逗號分隔的清單、以CIDR表示法列出所有的IPv4位址或IPv4子網路組合。

註 針對在CVS Google Cloud後端上建立的所有磁碟區、Trident會在儲存資源池上的所有標籤配置時複製到儲存磁碟區。儲存管理員可以定義每個儲存資源池的標籤、並將儲存資源池中建立的所有磁碟區分組。這是根據後端組態中提供的一組可自訂標籤、方便區分磁碟區的方法。

範例1：最低組態

這是絕對最低的後端組態。

下列StorageClass定義係指上述儲存資源池。使用 parameters.selector 欄位中、您可以為每個StorageClass指定用於裝載Volume的虛擬集區。該磁碟區會在所選的資源池中定義各個層面。

第一個StorageClass (cvs-extreme-extra-protection）對應至第一個虛擬儲存資源池。這是唯一提供極致效能、快照保留率為10%的資源池。最後一個StorageClass (cvs-extra-protection）撥出提供快照保留10%的任何儲存資源池。Astra Trident決定選取哪個虛擬儲存池、並確保符合快照保留需求。

建立後端組態檔之後、請執行下列命令：

tridentctl create backend -f <backend-file>

如果後端建立失敗、表示後端組態有問題。您可以執行下列命令來檢視記錄、以判斷原因：

tridentctl logs

識別並修正組態檔的問題之後、您可以再次執行create命令。
