> There could be cases where we find orphan data blocks not referenced by any tablet metadata:
> - Crash during a flush/compaction
> - Crash during a tablet copy could orphan the data blocks copied so far.
> - Bugs 
> In such situations, it is useful to have a manual tool to delete all the orphan data blocks for which there are no metadata.
