Types

type MountInfo

type MountInfo struct {
	DeviceID   string // device id: 0:137
	FSType     string // filesystem type: btrfs, nfs4, ext4
	RemotePath string // path to the server: 10.87.209.168:/serviced_var
	LocalPath  string // path on the client: /tmp/serviced/var
	ServerIP   string // server ip address: 10.87.209.168
}

MountInfo is retrieved from mountinfo

func GetMountInfo

func GetMountInfo(mountpoint string) (*MountInfo, error)

GetMountInfo gets the mount info of the mountpoint

type NFSDExportOptions

type NFSDExportOptions map[string]string

NFSDExportOptions are options specified in 'General Options' of exports manpage

type NFSMountInfo

type NFSMountInfo struct {
	// from findmnt
	MountInfo

	// from /proc/fs/nfsfs/volumes
	Version  string // nfsversion: v4, v3, ...
	ServerID string // id of server: 0a57d1a8
	Port     string // port on server: 801
	FSCache  string // whether fscache is used (yes/no)
}

NFSVolumeInfo is merged from mountinfo and volumes

func GetNFSVolumeInfo

func GetNFSVolumeInfo(mountpoint string) (*NFSMountInfo, error)

GetNFSVolumeInfo gets the NFSMountInfo of the mountpoint

type ProcNFSDExports

type ProcNFSDExports struct {
	MountPoint    string                       // exported path on the server: /exports/serviced_var
	ClientOptions map[string]NFSDExportOptions // keys are clients: 'Machine Name Formats' of exports manpage
}

ProcNFSDExports is a parsed representation of /proc/fs/nfs/exports information.

func GetProcNFSDExport

func GetProcNFSDExport(mountpoint string) (*ProcNFSDExports, error)

GetProcNFSDExport gets the export info to the mountpoint entry in /proc/fs/nfs/exports

func (*ProcNFSDExports) Equals

func (a *ProcNFSDExports) Equals(b *ProcNFSDExports) bool

Equals checks the equality of two ProcNFSDExports

type ProcStat struct {
	Pid      int    // The process ID.
	Filename string // The filename of the executable, in parentheses. This is visible whether or not the executable is swapped out.
	State    string // One character from the string "RSDZTW" where R is running, S is sleeping in an interruptible wait, D is waiting in uninterruptible disk sleep, Z is zombie, T is traced or stopped
	Ppid     int    // The PID of the parent.
	Pgrp     int    // The process group ID of the process.
	Session  int    // The session ID of the process.
}
