The Manager.MakeVolumeGroupID() function can be used to build a CSI VolumeGroupID from the backend (pool and name of the RBD-group). This will be used when checking if an RBD-image belongs to a group already. It is also possible to resolve the VolumeGroup by passing the VolumeGroupID to the existing Manager.GetVolumeGroupByID() function. Signed-off-by: Niels de Vos <ndevos@ibm.com>
