> Currently the StorageID is used to identify both the Datanode and the
> storage. This works because we treat all storages attached to the Datanode as
> a single storage unit.
> We plan to replace the StorageID with two independent IDs:
> # Datanode UUID - this will be a string that uniquely identifies each
> Datanode in the cluster. For upgraded clusters, the Datanode UUID will be the
> StorageID prior to the upgrade. i.e. we will reuse the prior Storage ID.
> # Storage UUID - Each storage attached to the datanode will be identified by
> a UUID.
