unmount method
Unmount a volume, or all volumes on its whole disk if wholeDisk is true.
Returns the unmounted volume, or the whole disk when wholeDisk is true.
Query the snapshot stream for individual volume states after a whole-disk
request. Active files can cause rejection; no force is used.
Implementation
@override
Future<DiskInfo> unmount(String diskId, {bool wholeDisk = false}) =>
_operate<Object?>('unmount', diskId, wholeDisk: wholeDisk)
.then(_decodeDisk);
