Functions ¶

func Has ¶

func Has(ctx context.Context, dev string, mnt string) (bool, error)

Has returns true when {dev} is mounted on {mnt} using the findmnt command

func HasFromMount ¶

func HasFromMount(dev string, mnt string) (bool, error)

HasFromMount returns true when {dev} is mounted on {mnt} using the mount command

func HasMntWithTypes ¶

func HasMntWithTypes(ctx context.Context, fsTypes []string, mnt string) (bool, error)

HasMntWithTypes returns true when a fs with type matching one of {fsTypes} is mounted on {mnt} using the findmnt command

Types ¶

type MountInfo ¶

type MountInfo struct {
	Source  string `json:"source"`
	Target  string `json:"target"`
	FsType  string `json:"fstype"`
	Options string `json:"options"`
}

func List ¶

func List(ctx context.Context, dev string, mnt string) (mounts []MountInfo, err error)

List return matching dev and mnt list of MountInfo. findmnt exec is used to do initial filtering, then filter on mnt is used (for nfs) + custom filter on [dev] for bind mounts.

We can't use findmnt -J -T {mnt} -S {dev} for nfs because it may hang. A timeout version of findmnt is not sufficient, we have to differentiate hang but mounted from not mounted.

So when dev is on nfs, We can't use findmnt -J -T {mnt} -S {dev} Instead findmnt -J -S {dev} is used, then mnt is filtered within List function.
