本页目录：

扩容类型为系统盘的云硬盘
当扩容类型为系统盘的云硬盘时，您可通过以下3种方式进行扩容。
﻿通过云服务器控制台扩容﻿
﻿通过云硬盘控制台扩容﻿
﻿通过 API 扩容﻿
扩容类型为数据盘的云硬盘
当扩容类型为数据盘的云硬盘时，您可通过以下3种方式进行扩容。
﻿通过云服务器控制台扩容﻿
﻿通过云硬盘控制台扩容﻿
﻿通过 API 扩容﻿
根据 CBS 数据盘可卸载属性的不同，您可选择不同的操作入口对数据盘进行扩容。
若当前硬盘为可卸载的 CBS 数据盘，您可经由云硬盘控制台或使用 扩容云硬盘 进行扩容操作。
若当前硬盘为不可卸载的 CBS 数据盘，您可经由云服务器实例控制台或使用 扩容云硬盘 进行扩容操作。
注意
如果云硬盘的最大容量仍无法满足您的业务需求，您可以使用 多块弹性云硬盘构建 RAID 组 或 多块弹性云硬盘构建 LVM 逻辑卷。
数据盘扩容完成后，需要进行相关后续操作才能为实例识别并使用：
扩容前
扩容后
后续操作
未创建文件系统
磁盘容量小于2TB
初始化云硬盘（小于2TB）
﻿
磁盘容量大于等于2TB
初始化云硬盘（大于等于2TB）
已创建文件系统
磁盘容量小于2TB
扩容的是 Windows 云服务器的云硬盘：扩展分区及文件系统（Windows）﻿
扩容的是 Linux 云服务器的云硬盘：扩展分区及文件系统（Linux）﻿
﻿
磁盘容量大于等于2TB
采用 GPT 分区格式： 扩展分区及文件系统（Windows）或 扩展分区及文件系统（Linux）。
采用 MBR 分区格式：不支持。
MBR 格式分区支持的磁盘最大容量为2TB。如果您的硬盘分区为 MBR 格式，且需要扩容到超过2TB时，建议您重新创建并挂载一块新的数据盘，然后使用 GPT 分区方式后将数据拷贝至新盘中。
﻿
费用说明
参考 扩容云硬盘计费说明。
