Cloning volumes

Limitations

You can clone volumes that are not attached to VMs or attached to stopped VMs.

Prerequisites

A volume is created, as described in Creating and deleting volumes.

To clone a volume

Admin panel

On the Compute > Storage > Volumes tab, click a volume.
On the volume right pane, click Clone.
In the Clone volume window, specify a volume name, size, and storage policy. Click Clone.

Command-line interface

Use the following command:

vinfra service compute volume clone --name <name> [--size <size-gb>]
                                    [--storage-policy <storage_policy>] <volume>

--name <name>: New volume name
--size <size-gb>: Volume size, in gigabytes
--storage-policy <storage_policy>: Storage policy ID or name
<volume>: Volume ID or name

For example, to clone the volume myvolume to myvolume2, run:

# vinfra service compute volume clone myvolume --name myvolume2
