Types

type Device

type Device map[string]string

func InitUdevDevice

func InitUdevDevice(udev map[string]string) Device

func (Device) GetDevName

func (device Device) GetDevName() string

GetDevName returns the path of device in /dev directory

func (Device) GetDevType

func (device Device) GetDevType() string

func (Device) GetIDPath

func (device Device) GetIDPath() string

GetIDPath returns the device id path

func (Device) GetIDType

func (device Device) GetIDType() string

func (Device) GetShortName

func (device Device) GetShortName() string

GetShortName returns the short device name of the /dev directory, e.g /dev/sda will return the name sda

func (Device) IsDisk

func (device Device) IsDisk() bool

IsDisk check if device is a disk

func (Device) IsPartition

func (device Device) IsPartition() bool

IsPartition check if device is a partition

type Udev

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

func NewUdev

func (*Udev) ActionHandler

func (u *Udev) ActionHandler(uevent netlink.UEvent)

func (*Udev) AddBlockDevice

func (u *Udev) AddBlockDevice(device *v1beta1.BlockDevice, autoProvisioned bool)

AddBlockDevice add new block device and partitions by watching the udev add action

func (*Udev) Monitor
