Creating an EVS Disk Using a Snapshot

Scenarios

This topic describes how to create an EVS disk on the EVS snapshot page. Besides, you can also create an EVS disk from a snapshot by specifying the Create from snapshot parameter on the disk creation page. For details, see Creating an EVS Disk.

When a disk is created from a snapshot, the created disk has the following constraints:
  • The disk type of the created disk will be consistent with that of the snapshot's source disk.
  • The device type of the created disk will be consistent with that of the snapshot's source disk.
  • A maximum of 128 disks can be created from this snapshot.
  • Batch disk creation is not possible, and the quantity parameter must be set to 1.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. Under Storage, click Elastic Volume Service.
  4. In the navigation tree on the left, choose Elastic Volume Service > Snapshots.

    The Snapshots page is displayed.

  5. In the snapshot list, locate the row that contains the target snapshot and click Create Disk in the Operation column.
  6. Set the EVS disk parameters. For details, see parameter descriptions and operations provided in Creating an EVS Disk.

    NOTE:

    A maximum of 128 disks can be created from a snapshot.

    If you create a disk from a snapshot, the disk capacity must be greater than or equal to the snapshot size. In the condition that you do not specify the disk capacity, if the snapshot size is smaller than 10 GB, the default capacity 10 GB will be used as the disk capacity; if the snapshot size is greater than 10 GB, the disk capacity will be consistent with the snapshot size.

  7. Click Create Now.
  8. On the Details page, check the disk information again.

    • If you do not need to modify the specifications, click Submit to start the creation.
    • If you need to modify the specifications, click Previous to modify parameters.

  9. In the disk list, view the disk status.

    If the disk status changes to Available, the disk is successfully created.
