type ReplicationDriver

type ReplicationDriver interface {
	// Any initialization the replication driver does while starting.
	Setup() error

	// NOTE Parameter vg means complete volume group information, because driver
	// may use it to do something and return volume group status.
	CreateVolumeGroup(opt *pb.CreateVolumeGroupOpts) (*model.VolumeGroupSpec, error)

	// NOTE Parameter addVolumesRef or removeVolumesRef means complete volume
	// information that will be added or removed from group. Driver may use
	// them to do some related operations and return their status.
	UpdateVolumeGroup(opt *pb.UpdateVolumeGroupOpts) (*model.VolumeGroupSpec, error)

	// NOTE Parameter volumes means volumes deleted from group, driver may use
	// their compelete information to do some related operations and return
	// their status.

	ListPools() ([]*model.StoragePoolSpec, error)
}

VolumeDriver is an interface for exposing some operations of different volume drivers, currently support sample, lvm, ceph, cinder and so forth.
