擴容一塊磁碟，支援擴容系統磁碟和資料磁碟。
介面說明
擴容前，請務必查詢雲端硬碟採用的分割區格式。如果是 MBR 格式，不支援擴容到 2TiB 以上，否則會造成資料遺失。對於 MBR 分割區擴容，建議您重新建立並掛載一塊資料磁碟，採用 GPT 分割區格式後，再將已有資料複製至新的資料磁碟上。更多詳情，請參見擴容雲端硬碟容量。
-
支援擴容的磁碟類型包括普通雲端硬碟（
cloud）、高效雲端硬碟（cloud_efficiency）、SSD 雲端硬碟（cloud_ssd）、ESSD 雲端硬碟（cloud_essd）、ESSD AutoPL 雲端硬碟（cloud_auto）、彈性臨時磁碟-標準版（elastic_ephemeral_disk_standard）和彈性臨時磁碟-進階版（elastic_ephemeral_disk_premium）、 ESSD 同城冗餘雲端硬碟（cloud_regional_disk_auto）。 -
正在建立快照的雲端硬碟不支援擴容。請您等待快照建立完成後，再開始執行擴容操作。
-
該介面不能擴容分割區和檔案系統，您需要在擴容雲端硬碟容量後自行分配分割區和檔案系統，具體操作，請參見擴容分割區與檔案系統（Linux）和擴容分割區與檔案系統（windows）。
-
開啟多重掛載特性的雲端硬碟支援線上擴容和離線擴容，請確保磁碟掛載的執行個體滿足以下條件：
線上擴容時，執行個體狀態為執行中（
Running）。離線擴容時，執行個體狀態為執行中（
Running）或已停止（Stopped）。
-
請確保雲端硬碟滿足以下條件：
