> This Jira proposes the following:
> # Implement HDDSVolume to encompass VolumeInfo along with other HDDS
> specific fields.
> ** VolumeInfo container disk specific information such as capacity, usage,
> storageType. HddsVolume has hdds specific fields for volume such as
> VolumeState, VolumeStats (will be added later).
> # Write volume level Version file
> ** clusterID, storageID, datanodeUUID, creationTime and layoutVersion.
> # Read Version file while instantiating HDDSVolumes.
> ** When the volume Version file already exists (for example, when a DN is
> restarted), then the version file is read for the stored clusterID,
> datanodeUuid, lahyoutVersion etc. Some checks will be performed to verify the
> sanity of the volume.
> ** When a fresh Datanode is started, the Version file is not written to the
> volume uptill the clusterID is received from the SCM.
