Overview ¶
Package mount defines an interface to mounting filesystems.
TODO(thockin): This whole pkg is pretty linux-centric. As soon as we have an alternate platform, we will need to abstract further.

Functions ¶
func GetDeviceNameFromMount ¶ added in v0.15.0
GetDeviceNameFromMount: given a mnt point, find the device from /proc/mounts returns the device name, reference count, and error code
Types ¶
type FakeAction ¶ added in v0.13.1
type FakeAction struct {
Action string // "mount" or "unmount"
Target string // applies to both mount and unmount actions
Source string // applies only to "mount" actions
FSType string // applies only to "mount" actions
}
FakeAction objects are logged every time a fake mount or unmount is called.
type FakeMounter ¶ added in v0.13.0
type FakeMounter struct {
MountPoints []MountPoint
Log []FakeAction
}
FakeMounter implements mount.Interface for tests.
func (*FakeMounter) IsMountPoint ¶ added in v0.15.0
func (f *FakeMounter) IsMountPoint(file string) (bool, error)
func (*FakeMounter) List ¶ added in v0.13.0
func (f *FakeMounter) List() ([]MountPoint, error)
func (*FakeMounter) ResetLog ¶ added in v0.13.1
func (f *FakeMounter) ResetLog()
type Interface ¶
type Interface interface {
// Mount wraps syscall.Mount().
Mount(source string, target string, fstype string, flags uintptr, data string) error
// Umount wraps syscall.Mount().
Unmount(target string, flags int) error
// List returns a list of all mounted filesystems. This can be large.
// On some platforms, reading mounts is not guaranteed consistent (i.e.
// it could change between chunked reads). This is guaranteed to be
// consistent.
List() ([]MountPoint, error)
// IsMountPoint determines if a directory is a mountpoint.
IsMountPoint(file string) (bool, error)
}
Each supported platform must define the following flags:
- FlagBind: specifies a bind mount
- FlagReadOnly: the mount will be read-only
type MountPoint ¶
This represents a single line in /proc/mounts or /etc/fstab.
type Mounter ¶ added in v0.10.0
type Mounter struct{}
Mounter implements mount.Interface for linux platform.
func (*Mounter) IsMountPoint ¶ added in v0.15.0
IsMountPoint determines if a directory is a mountpoint, by comparing the device for the directory with the device for it's parent. If they are the same, it's not a mountpoint, if they're different, it is.
func (*Mounter) List ¶ added in v0.10.0
func (*Mounter) List() ([]MountPoint, error)
List returns a list of all mounted filesystems.
