func GetAllTypes

func GetAllTypes(BL *v1alpha1.BlockDeviceList) error

GetAllTypes updates the list of all block devices found on nodes and their relationships

Types

type AllBlockDevices

type AllBlockDevices struct {
	Parents    []string
	Partitions []string
	LVMs       []string
	RAIDs      []string
