Types

type DeviceUtils

type DeviceUtils interface {
	// GetDiskByIdPaths returns a list of all possible paths for a
	// given Persistent Disk
	GetDiskByIdPaths(deviceName string, partition string) []string

	// VerifyDevicePath returns the first of the list of device paths that
	// exists on the machine, or an empty string if none exists
	VerifyDevicePath(devicePaths []string, deviceName string) (string, error)

	// DisableDevice performs necessary disabling prior to a device being
	// detached from a node. The path is that from GetDiskByIdPaths.
	DisableDevice(devicePath string) error

	// Resize returns whether or not a device needs resizing.
	Resize(resizer resizefs.Resizefs, devicePath string, deviceMountPath string) (bool, error)

	// IsDeviceFilesystemInUse returns if a device path with the specified fstype
	// TODO: Mounter is passed in in order to call GetDiskFormat()
	// This is currently only implemented in mounter_linux, not mounter_windows.
	// Refactor this interface and function call up the stack to the caller once it is
	// implemented in mounter_windows.
