ResizeVolume

1. Description

You can call this operation to expand the capacity of the specified EBS volume.

Note:
The maximum capacity of an EBS volume that uses MBR partitioning is 2 TB. If the capacity exceeds this limit, the excess capacity cannot be used. You may need to expand the capacity of an EBS volume that uses MBR partitioning to more than 2 TB. In this case, we recommend that you create and attach a data disk that uses GPT partitioning and then copy the data to the new disk.

Limits:

1. You can expand but not shrink the capacity of an EBS volume.
2. The types of EVS disks that support capacity expansion include: ESSD EBS volume (ESSD_PL1/ESSD_PL2/ESSD_PL3), EHDD, and SSD3.0 EBS volume (SSD3.0).
3. You can expand the capacity of EBS volumes in the available state offline.
4. If an EBS volume is attached to a KEC instance, you can expand the capacity of the EBS volume only when the KEC instance is in the active or stopped state. For more information about the limits on online and offline capacity expansion in different operating systems, see Overview.
5. After the capacity of an EBS volume is expanded, the partition information and file system of the EBS volume are not automatically modified. You must manually format the extended storage space as required.
