The rbdSnapshot/rbdImage object implements all functions for a useful Snapshot interface. The rbd.Manager will be able to use this for providing VolumeGroupSnapshot support. Signed-off-by: Niels de Vos <[email protected]>

Each object is responsible for maintaining a connection to the journal. By sharing a single journal, cleanup of objects becomes more complex as the journal is used in deferred functions and only the last should destroy the journal connection resources. Signed-off-by: Niels de Vos <[email protected]>
The NewSnapshotByID() function makes it possible to clone a new Snapshot from an existing RBD-image and the ID of an RBD-snapshot on that image. This will be used by the VolumeGroupSnapshot feature, where the ID of an RBD-snapshot is obtained for the RBD-snapshot on the RBD-images. Signed-off-by: Niels de Vos <[email protected]>
When the rbd.Manager creates a VolumeGroupSnapshot, each RBD-snapshot that is created as part of the RBD-group needs to be cloned into its own RBD-image that will be used as a CSI Snapshot. The VolumeGroup.CreateSnapshots() creates the RBD-group snapshot and returns a list of the Snapshot structs. Signed-off-by: Niels de Vos <[email protected]>
The VolumeGroupSnapshot type will be used by the rbd.Manager to create, inspect and delete VolumeGroupSnapshos. Signed-off-by: Niels de Vos <[email protected]>
A (CSI) VolumeGroupSnapshot object contains references to Snapshot IDs (or CSI Snapshot handles). In order to work with a VolumeGroupSnapshot struct, the Snapshot IDs need to be resolved into rbdSnapshot structs. Signed-off-by: Niels de Vos <[email protected]>
Implement the CreateVolumeGroupSnapshot for the rbd.Manager. A Group Controller Server can use the rbd.Manager to create VolumeGroupSnapshots in an easy an idempotent way. Signed-off-by: Niels de Vos <[email protected]>

When the GroupSnapGetInfo go-ceph function is supported by librbd, the Group Controller Servive and VolumeGroupSnapshot capabilities can be exposed to the Container Orchestrator. Signed-off-by: Niels de Vos <[email protected]>
