Basic volume operations

Changing the volume type

You can change the type of your volume if your business needs change to get the performance you need. This topic explains how to change the volume type.

Before you begin

EBS only allows you to change the following types of volumes: ESSD PL0, ESSD PL1, and ultral disk. For more information about volume types, see Volume specifications.

Different volume types have different performance limits. Changing the volume type may affect your business. Make sure you understand the different types before changing to ensure they meet your requirements. We recommend changing the volume type during off-peak hours.

Notes

Category	Description
Restrictions before change	You can only change a volume's type when it is in the "Attached" or "Available" status. The corresponding ECS instance cannot expire and the account cannot be in arrears if the volume is in "Attached" status. Otherwise, it is not possible to change the volume's type.
Restrictions during change	You cannot perform the following operations when a volume is in the "Modifying" status: Extending, attaching, detaching, deleting, modifying, canceling, migrating, or rolling back a volume Changing the billing method from pay-as-you-go to subscription Partitioning and formatting a volume Creating a snapshot Changing the operating system for the ECS instance, or resetting the system volume
Restricted operations	Once a volume type change is triggered, it cannot be canceled.
Billing	The billing rules for the volume will change once you have modified its type. For more information, see Billing rules for resource changes.
Backup	We recommend creating a snapshot to back up your data before changing a volume's type. For more information, see Creating snapshots.
