Overview

Package volumes provides information and interaction with volumes in the OpenStack Block Storage service. A volume is a detachable block storage device, akin to a USB hard drive. It can only be attached to one instance at a time.

Example to create a Volume from a Backup 

backupID := "20c792f0-bb03-434f-b653-06ef238e337e"
options := volumes.CreateOpts{
	Name:     "vol-001",
	BackupID: &backupID,
}

client.Microversion = "3.47"
volume, err := volumes.Create(client, options).Extract()
if err != nil {
	panic(err)
}

fmt.Println(volume)

Functions

func ExtractVolumesInto 

func ExtractVolumesInto(r pagination.Page, v interface{}) error
