Functions ¶

func GetFid ¶

func GetFid(path string) (*lustre.Fid, error)

GetFid retuns the lustre.Fid for the path name.

func GetFidFd ¶

func GetFidFd(fd int) (*lustre.Fid, error)

GetFidFd retuns the lustre.Fid for the path name.

Types ¶

type LinkEntry ¶

type LinkEntry struct {
	Name   string
	Parent lustre.Fid
}

LinkEntry is an entry from the link extended attribute on a Lustre file. Each entry represents a name for hardlink and parent directory that conatains that name.

func GetLinkEA ¶

func GetLinkEA(path string) ([]LinkEntry, error)

GetLinkEA returns the link extended attribute for a file or error if there is no link attribute. Pretty fragile since we're hardcoding all the struct sizes here.

type Version ¶

type Version struct {
	Lustre string `yaml:"lustre"`
	Kernel string `yaml:"kernel"`
	Build  string `yaml:"build"`
}

Version represents the version of Lustre.

func GetVersion ¶

func GetVersion() (*Version, error)

GetVersion returns current Lustre version.
