Deleting Pay-per-Use EVS Disks

Scenarios

If an EVS disk is no longer used, you can release the virtual resources by deleting it.

After a disk is deleted, you are no longer charged for it. EVS immediately destroys the metadata so that data can no longer be accessed. In addition, the physical storage space of the disk is reclaimed and cleared before being re-assigned. For any new disk created based on the re-assigned physical space, before data is written to the disk, EVS returns zero for all the read and write requests to the disk.

When deleting a disk, you can choose not to delete the disk immediately, but move it to the recycle bin to prevent any data loss that may be caused by unintended operations. The recycle bin function is disabled by default. If you need to use this function, enable it on the management console. For details, see Enabling the Recycle Bin.

  • Pay-per-use disk:
    It can only be deleted when the following conditions are met:
    • The disk status is Available, Error, Expansion failed, Restoration failed, or Rollback failed.
    • The disk is not added to any replication pair in the Storage Disaster Recovery Service (SDRS). For any disk already added to a replication pair, you need to first delete the replication pair and then delete the disk.
    • The disk is not locked by any service.
    • The shared disk has been detached from all its servers.

When you delete a disk, all the disk data including the snapshots created for this disk will be deleted.

Procedure

  1. Log in to the management console.
  2. Under Storage, click Elastic Volume Service.

    The disk list page is displayed.

  3. In the disk list, locate the row that contains the target disk, click More in the Operation column, and choose Delete.
  4. (Optional) If multiple disks are to be deleted, select in front of each disk and click Delete in the upper area of the list.
  5. In the displayed dialog box, confirm the information.

    • If recycle bin is not enabled, click Yes to delete the disk.

      When the disk is no longer displayed in the disk list, the deletion is successful.

    • If recycle bin is enabled:
      • Select Destroy disks and not put them into the recycle bin and click Destroy to destroy the disk.

        When the disk is no longer displayed in the disk list, the deletion is successful.

      • Click Move to Recycle Bin to move disk into the recycle bin.

        If the disk is displayed in the recycle bin and the disk status is To be destroyed, the disk has been put into the recycle bin.
