Functions

func ForceMount

func ForceMount(device, target, mType, options string) error

ForceMount will mount a filesystem according to the specified configuration, *regardless* if the target path is not already mounted. Options must be specified like the mount or fstab unix commands: "opt1=val1,opt2=val2". See flags.go for supported option flags.

func ForceUnmount

func ForceUnmount(target string) (err error)

ForceUnmount will force an unmount of the target filesystem, regardless if it is mounted or not.

func Mount

func Mount(device, target, mType, options string) error

Mount will mount filesystem according to the specified configuration, on the condition that the target path is *not* already mounted. Options must be specified like the mount or fstab unix commands: "opt1=val1,opt2=val2". See flags.go for supported option flags.

func Mounted

func Mounted(mountpoint string) (bool, error)

Mounted looks at /proc/self/mountinfo to determine of the specified mountpoint has been mounted

func Unmount

func Unmount(target string) error

Unmount will unmount the target filesystem, so long as it is mounted.

Types

type Info

type Info struct {
	// ID is a unique identifier of the mount (may be reused after umount).
	ID int

	// Parent indicates the ID of the mount parent (or of self for the top of the
	// mount tree).
	Parent int

	// Major indicates one half of the device ID which identifies the device class.
	Major int

	// Minor indicates one half of the device ID which identifies a specific
	// instance of device.
	Minor int

	// Root of the mount within the filesystem.
	Root string

	// Mountpoint indicates the mount point relative to the process's root.
	Mountpoint string

	// Opts represents mount-specific options.
	Opts string

	// Optional represents optional fields.
	Optional string

	// Fstype indicates the type of filesystem, such as EXT3.
	Fstype string

	// Source indicates filesystem specific information or "none".
	Source string

	// VfsOpts represents per super block options.
	VfsOpts string
}

Info reveals information about a particular mounted filesystem. This struct is populated from the content in the /proc/<pid>/mountinfo file.

func GetMounts

func GetMounts() ([]*Info, error)

GetMounts retrieves a list of mounts for the current running process.
