Help Center/ Elastic Volume Service/ User Guide/ Detaching and Deleting an EVS Disk/ Unsubscribing from or Deleting an EVS Disk

Unsubscribing from or Deleting an EVS Disk

Updated on 2024-12-26 GMT+08:00

Scenarios

If an EVS disk is no longer used, you can delete the disk to release the virtual resources. When a disk is deleted, EVS immediately destroys the metadata to ensure 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 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 console. For details, see Enabling the Recycle Bin.

Yearly/Monthly disks cannot be deleted. You can unsubscribe from them if needed. System disks must be unsubscribed from together with their servers. For how to unsubscribe from data disks, see Table 1.

Table 1 Unsubscription scenarios of data disks

You will be not billed for a disk after it is deleted or unsubscribed from.

Notes and Constraints

  • The disk status is Available, Error, Expansion failed, Restoration failed, or Rollback failed.
  • The disk is not locked by any service.
  • The shared disk has been detached from all its servers.
  • 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.
  • Yearly/Monthly system disks cannot be unsubscribed from separately. They must be unsubscribed from together with their servers.
  • Non-shared, yearly/monthly data disks purchased together with or later added to a yearly/monthly server have the same expiration time as the server. They can be unsubscribed from together with the server or separately when their statuses are In-use, Available, or Error.
  • Yearly/Monthly data disks purchased on the EVS console have different expiration times as the server. They can be unsubscribed from separately.
NOTICE:

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