Functions

func DevForPartitionLabel

func DevForPartitionLabel(devname, label string) (*blockdevice.BlockDevice, error)

DevForPartitionLabel finds and opens partition as a blockdevice.

func GetPartitionWithName

func GetPartitionWithName(name string) (*gpt.Partition, error)

GetPartitionWithName probes all known block device's partition table for a parition with the specified name.

Types

type ProbedBlockDevice

type ProbedBlockDevice struct {
	*blockdevice.BlockDevice

	SuperBlock filesystem.SuperBlocker
	Path       string
}

ProbedBlockDevice represents a probed block device.

func All

func All(options ...SelectOption) ([]*ProbedBlockDevice, error)

All probes a block device's file system for the given label.

func GetDevWithFileSystemLabel

func GetDevWithFileSystemLabel(value string) (*ProbedBlockDevice, error)

GetDevWithFileSystemLabel probes all known block device's file systems for the given label.

func GetDevWithPartitionName

func GetDevWithPartitionName(name string) (*ProbedBlockDevice, error)

GetDevWithPartitionName probes all known block device's partition table for a parition with the specified name.

type SelectOption

type SelectOption func(device *ProbedBlockDevice) (bool, error)

SelectOption is a callback matcher for All block devices probes.

func WithFileSystemLabel

func WithFileSystemLabel(label string) SelectOption

WithFileSystemLabel searches for a block device which has filesystem labeled with the provided label.

func WithPartitionLabel

func WithPartitionLabel(label string) SelectOption

WithPartitionLabel search for a block device which has partitions with some specific label.

func WithSingleResult

func WithSingleResult() SelectOption

WithSingleResult enforces a single result from All function.
