Abstract:
Techniques for shrinking a filesystem backed by a volume identify slices in the volume to be evacuated in order to reach a target size, identify a target endpoint in the volume, and evacuate identified slices to available locations prior to the target endpoint. The same data is typically not moved from slice to slice multiple times.
