    Add a new instance query flag ‘disk_usage’ · 024e157f

    This patch adds a new instance query flag called disk_usage that
    retrieves the overall space used by an instance on each of its nodes.
    This can be used when balancing the cluster or checking N+1 status.
    The flag is also exported in RAPI. Note the flag is currently broken for
    file-based instances, as it represents the amount of space in the
    cluster volume group.
