Functions

func GetAvailableDevices

func GetAvailableDevices(ctx context.Context, clusterdContext *clusterd.Context, nodeName, clusterName string, devices []cephv1.Device, filter string, useAllDevices bool) ([]cephv1.Device, error)

GetAvailableDevices conducts outer join using input filters with free devices that a node has. It marks the devices from join result as in-use.

func ListDevices

func ListDevices(ctx context.Context, clusterdContext *clusterd.Context, namespace, nodeName string) (map[string][]sys.LocalDisk, error)

ListDevices lists all devices discovered on all nodes or specific node if node name is provided.

func ListDevicesInUse

func ListDevicesInUse(ctx context.Context, clusterdContext *clusterd.Context, namespace, nodeName string) ([]sys.LocalDisk, error)

ListDevicesInUse lists all devices on a node that are already used by existing clusters.

Types

type Discover

type Discover struct {
	// contains filtered or unexported fields
}
