Variables

var ErrNoPartitionTable = errors.New("no Partition Table Found")

ErrNoPartitionTable is returned if there is no partition table.

Functions

func Ceiling

func Ceiling(val, unit uint64) uint64

Ceiling returns the smallest integer equal to or larger than val that is evenly divisible by unit.

func Floor

func Floor(val, unit uint64) uint64

Floor returns the largest integer equal to or less than val that is evenly divisible by unit.

func GetPartitionKname

func GetPartitionKname(diskName string, num uint) string

GetPartitionKname - get the name of the num partition device on diskName

func GetPartitionsBlockDevice

func GetPartitionsBlockDevice(dev string) (string, error)

GetPartitionsBlockDevice - return the block device name ('sda') given input of a partition, either kname (sda1) or /dev/sda1. Can also be called on a disk and will return the disk.

func GetSysPaths

func GetSysPaths(driverSysPath string) []string

func GetUdevInfo

func GetUdevInfo(kname string) (disko.UdevInfo, error)

GetUdevInfo return a UdevInfo for the device with kernel name kname.

func IsSysPathRAID

func IsSysPathRAID(syspath string, driverSysPath string) bool

IsSysPathRAID - is this sys path (udevadm info's DEVPATH) on a scsi controller.

syspath will look something like
   /devices/pci0000:3a/0000:3a:02.0/0000:3c:00.0/host0/target0:2:2/0:2:2:0/block/sdc

func NameByDiskID

func NameByDiskID(driverSysPath string, id int) (string, error)

NameByDiskID - return the linux name (sda) for the disk with given DiskID

func System

func System() disko.System

System returns an linux specific implementation of disko.System interface.

func VolumeManager

func VolumeManager() disko.VolumeManager

VolumeManager returns the linux implementation of disko.VolumeManager interface.
