Deleting an EVS Disk

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.
