If you want to continue to use an EBS volume, you need to renew the EBS volume before it expires. After an EBS volume expires, it will be detached from the corresponding KEC instance and data cannot be read or written.
Log in to the EBS console.
On the EBS tab, select the target EBS volumes in Subscription mode and click Renew/Trial Extension to renew multiple volumes at a time. Alternatively, choose More > Renew in the Operation column to renew a single EBS volume.
In the dialog box that appears, select a renewal period and click Renew.
We recommend that you enable automatic renewal when you purchase an EBS volume in Subscription mode. The automatic renewal feature renews your cloud resources regularly and notifies you of the renewal result by sending you SMS messages and emails. It saves your time and prevents the service from being suspended in case you forget to renew the volume.
Note: To enable automatic renewal, you need to ensure sufficient account balance. If an EBS volume fails to be automatically renewed seven days before it expires due to insufficient account balance, a deduction is automatically made again three days before the expiration. If the deduction is successful, the volume is automatically renewed in the week. If the deduction fails, another deduction is made one day before the expiration. After the expiration, the service is automatically suspended. During the resource retention period, you need to manually renew the EBS volume.
