Functions

func BytesToGiB

func BytesToGiB(volumeSizeBytes int64) int64

BytesToGiB conversts Bytes to GiB

func ConvertTagsToMap

func ConvertTagsToMap(tags string, tagsDelimiter string) (map[string]string, error)

ConvertTagsToMap convert the tags from string to map, default tagDelimiter is "," the valid tags format is "key1=value1,key2=value2", which could be converted to {"key1": "value1", "key2": "value2"}

func GetElementsInArray1NotInArray2

func GetElementsInArray1NotInArray2(arr1 []int, arr2 []int) []int

func GiBToBytes

func GiBToBytes(volumeSizeGiB int64) int64

GiBToBytes converts GiB to Bytes

func IsLinuxOS

func IsLinuxOS() bool

IsLinuxOS decides whether the driver is running on linux OS.

func IsWindowsOS

func IsWindowsOS() bool

IsWindowsOS decides whether the driver is running on windows OS.

func MakeDir

func MakeDir(pathname string) error

func MakeFile

func MakeFile(pathname string) error

func RoundUpBytes

func RoundUpBytes(volumeSizeBytes int64) int64

RoundUpBytes rounds up the volume size in bytes up to multiplications of GiB in the unit of Bytes

func RoundUpGiB

func RoundUpGiB(volumeSizeBytes int64) int64

RoundUpGiB rounds up the volume size in bytes up to multiplications of GiB in the unit of GiB

func RoundUpSize

func RoundUpSize(volumeSizeBytes int64, allocationUnitBytes int64) int64

RoundUpSize calculates how many allocation units are needed to accommodate a volume of given size. E.g. when user wants 1500MiB volume, while AWS EBS allocates volumes in gibibyte-sized chunks, RoundUpSize(1500 * 1024*1024, 1024*1024*1024) returns '2' (2 GiB is the smallest allocatable volume that can hold 1500MiB)

Types

type VolumeLocks

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

func NewVolumeLocks

func NewVolumeLocks() *VolumeLocks

func (*VolumeLocks) Release

func (vl *VolumeLocks) Release(volumeID string)

func (*VolumeLocks) TryAcquire

func (vl *VolumeLocks) TryAcquire(volumeID string) bool
