Cloning a volume

Cloning is the recommended method for copying volumes. While it is possible to make an image of an existing volume and use it to create a new volume, cloning is much faster and requires less movement of data behind the scenes. This method is handy if you have a persistent VM and you want to test out something before doing it on your production site. It is highly recommended to shut down your VM before creating a clone of the volume as the newly created volume may be left in an inconsistent state if there was writing to the source volume during the time the clone was created. To create a clone you must use the command line client with this command

[name@server ~]$ openstack volume create --source <source-volume-id> --size <size-of-new-volume> <name-of-new-volume>
