Lustre Utils API for Go

This package is a Go interface for liblustreapi. Instead of a 1:1 representaiton of liblustre, it attempts to present a more Go-friendly interface. It is still a work in progress, and interfaces could still change.

Constants

const (
	// AcceptorPort is the port used for LNet traffic over TCP
	AcceptorPort = 988

	// MaxExtentLength is a value sent by the coordinator to
	// signify that an action should apply from the offset to
	// EOF. In liblustreapi, this is represented by
	// math.MaxUint64.
	MaxExtentLength int64 = -1
)

Variables

var ErrUnimplemented = errors.New("not implemented")

ErrUnimplemented is returned when a function is not available on the current platform.

Types

type Fid

type Fid struct {
	Seq uint64
	Oid uint32
	Ver uint32
}

Fid is a pure Go representation of a Lustre file identifier. It is intended to be the only representation of a Lustre Fid outside of llapi.

func ParseFid

func ParseFid(fidstr string) (*Fid, error)

ParseFid converts a fid in string format to a Fid

func (*Fid) IsDotLustre

func (f *Fid) IsDotLustre() bool

IsDotLustre is true if Fid is special .lustre entry.

func (*Fid) IsZero

func (f *Fid) IsZero() bool

IsZero is true if Fid is 0.

func (*Fid) MarshalJSON

func (f *Fid) MarshalJSON() ([]byte, error)

MarshalJSON converts a Fid to a string for JSON.

func (*Fid) String

func (f *Fid) String() string

func (*Fid) UnmarshalJSON

func (f *Fid) UnmarshalJSON(b []byte) (err error)

UnmarshalJSON converts fid string to Fid.
