This article is about how to create a new empty cloud disk on the ECS console. The editor thinks it is very practical, so I hope you can get something after reading this article. Let's take a look at it with the editor.

Create a 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.

Matters needing attention

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

Cloud disks created in this way can only be billed by postpaid and can only be used as data disks.

Description

You can create a cloud disk as a data disk when you create an ECS instance. The billing method of the cloud disk created in this way is the same as that of the instance.

You can create an entirely new empty cloud disk, or you can create a cloud disk with snapshots.

The limit of postpaid cloud disks created by each account for data disks in all regions = the number of postpaid instances of the account in all regions * 5. For more information, see usage restrictions.

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

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

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

If the cloud disk is mounted on a prepaid instance, convert the postpaid cloud disk to a prepaid cloud disk by upgrading the configuration of the prepaid instance.

If the cloud disk is mounted on a postpaid instance, the postpaid cloud disk will be converted to a prepaid cloud disk by changing postpaid to prepaid.

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

prerequisite

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

Your account balance must not be less than 100 yuan or equivalent vouchers or coupons. This is because the separately created cloud disks are billed by quantity.

The region and availability zone where the instance of the cloud disk needs to be mounted. 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 encryption. 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 creation page.

Select the region and availability zone.

Description

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 it is encrypted, and set the purchase quantity. You can also choose to create a cloud disk with snapshots.

Confirm the current configuration and configuration costs.

Click Buy now and follow the page guide to complete the creation.

After the creation is successful, go back 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.

Subsequent operation

Mount the cloud disk
