Functions ¶

func CreateDevice ¶

func CreateDevice(name string, flags CreateFlags, targets []Target) (_ string, err error)

CreateDevice creates a device-mapper device with the given target spec. It returns the path of the new device node.

func RemoveDevice ¶

func RemoveDevice(name string) error

RemoveDevice removes a device-mapper device and its associated device node.

Types ¶

type CreateFlags ¶

type CreateFlags int

CreateFlags modify the operation of CreateDevice

const (
	// CreateReadOnly specifies that the device is not writable
	CreateReadOnly CreateFlags = 1 << iota
)

type Target ¶

type Target struct {
	Type                string
	SectorStart, Length int64
	Params              string
}

Target specifies a single entry in a device's target specification.

func LinearTarget ¶

func LinearTarget(sectorStart, length int64, path string, deviceStart int64) Target

LinearTarget constructs a device-mapper target that maps a portion of a block device at the specified offset.
