      If OSTs are permanently deactivated via lctl conf_param <fsname>.OSTnnnn.active=0 they still appear in the lfs df output, which can be annoying to users.

      If the OST is permanently deactivated (as opposed to disconnected or otherwise unavailable due to error) don't list the OST in lfs df unless -v is also given. That will remove this annoying output from normal usage, but still allow the full OST listing to be generated if needed for some reason.
