How to create a new empty cloud disk separately on the ECS console

This article introduces how to create a new empty cloud disk separately on the ECS console, and focuses on the specific operation steps.

Create cloud disk

You can create a cloud disk separately through the console or API interface to increase the storage space of the system. This article describes how to create a new empty cloud disk separately on the ECS console.

Notes

Before creating a cloud disk, you need to know the following information:

The cloud created in this way Disks can only be billed in a pay-as-you-go manner, and can only be used as data disks.

Note

You can create a cloud disk as a data disk when creating an ECS instance. The cloud disk created in this way is billed in the same way as the instance.

You can create a new empty cloud disk or use a snapshot to create a cloud disk.

The limit of pay-as-you-go cloud disks created as data disks for each account in all regions = the number of pay-as-you-go instances for this account in all regions * 5. See Usage Restrictions for details.

Currently, cloud server ECS does not support merging multiple cloud disks. After a cloud disk is created, each cloud disk is an independent entity, and multiple cloud disk spaces cannot be merged together through formatting. It is recommended that you plan the number and capacity of cloud disks in advance.

It is not recommended to create logical volumes such as LVM (Logical Volume Manager) for multiple cloud disks that have been created. Because snapshots can only be created for each independent cloud disk, after using LVM, data differences will occur when rolling back the cloud disk using snapshots.

After creation, you can convert the billing method of the cloud disk:

If the cloud disk is mounted on a prepaid instance, upgrade the configuration of the prepaid instance to convert the pay-as-you-go cloud disk to Prepaid cloud storage.

If the cloud disk is mounted on a pay-as-you-go instance, convert the pay-as-you-go cloud disk to a prepaid cloud disk through Pay-As-You-Go to Prepaid.

For cloud disks created in this way, as long as the billing method is not converted, you can uninstall the cloud disk and release the cloud disk at any time.

Prerequisites

Before creating a cloud disk, you must confirm the following information:

Your account balance must not be less than 100 yuan or equivalent voucher or coupon. Because cloud disks created separately adopt a pay-as-you-go method.

The region and availability zone where the instance to which the cloud disk needs to be mounted is located. When mounting a cloud disk, the instance and the cloud disk must be in the same region and availability zone.

Whether the cloud disk needs to be encrypted. For more information, see ECS Disk Encryption.

Operation steps

Log in to the ECS management console.

In the left navigation bar, click Storage > Cloud Disk.

In the upper right corner of the Disk List page, click Create Cloud Disk to enter the Create page.

Select a region and availability zone.

Note

When mounting a cloud disk, the instance and the cloud disk must be in the same region and availability zone.

Select the type and size of the cloud disk, confirm whether to encrypt it, and set the purchase amount. You can also choose to create a cloud disk from a snapshot.

Confirm the current configuration and configuration fee.

Click Buy Now and follow the page guidance to complete creation.

After the creation is successful, return to the disk list page and refresh the list. You can see the newly created cloud disk and the disk status is displayed as To be mounted.
