When the CBS space is insufficient to meet the data storage requirements of your business, you can increase capacity by scaling out to avoid service disruptions or data loss due to insufficient capacity.

CBS Expansion Process

I. Expanding CBS Capacity

When CBS space is insufficient, you first need to expand the cloud disk capacity. You can choose different methods for capacity expansion. For details, see Step 1: Cloud Disk Expansion.

II. Expanding Partitions and File Systems

After the CBS expansion is complete, you must perform the required follow-up operations for the instance to recognize and use it.

Expanded CBS capacity is greater than 2 TiB and the partition table format is GPT.
Expanded CBS capacity is greater than 2 TiB and the partition table format is MBR.
Note: The maximum disk capacity supported by an MBR partition is 2 TiB. If your disk partition is in MBR format and you need to expand it beyond 2 TiB, you must first convert the MBR partition to GPT. Please refer to the steps in Extend Partitions and File Systems (Linux) to proceed.
