    image: 1d7d2f6e-2843-43e3-9337-cb9778fb6ac5
    file format: qcow2
    virtual size: 80G (85899345920 bytes)
    disk size: 2.4G
    cluster_size: 65536
    Format specific information:
        compat: 1.1
        lazy refcounts: false

Finally change your flavor disk space to “virtual size”,

in this case is 80G.

    # nova flavor-list --all | grep your-flavor-name
    # nova flavor-show your-flavor-id
    
    Go to dashboard and edit flavor ( disk size = 80 )
