Hi, Geoff,
  Thanks, while I think they are mostly DATA volumes as what I see on the
UI, but shouldn't they will be deleted automatically after a VM instance
has been deleted and expunged? Or one has to delete DATA volumes explicitly
by hand( if so, finding out which DATA volume belongs to which VM will be a
problem, as the VM has already gone)?
