Functions ¶
func ForceMount ¶
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 ¶
ForceUnmount will force an unmount of the target filesystem, regardless if it is mounted or not.
func MakePrivate ¶ added in v0.4.2
MakePrivate ensures a mounted filesystem has the PRIVATE mount option enabled. See the supported options in flags.go for further reference.
func MakeRPrivate ¶ added in v0.4.2
MakeRPrivate ensures a mounted filesystem has the RPRIVATE mount option enabled. See the supported options in flags.go for further reference.
func MakeRShared ¶ added in v0.4.2
MakeRShared ensures a mounted filesystem has the RSHARED mount option enabled. See the supported options in flags.go for further reference.
func MakeRSlave ¶ added in v0.4.2
MakeRSlave ensures a mounted filesystem has the RSLAVE mount option enabled. See the supported options in flags.go for further reference.
func MakeRUnbindable ¶ added in v0.4.2
MakeRUnbindable ensures a mounted filesystem has the RUNBINDABLE mount option enabled. See the supported options in flags.go for further reference.
func MakeShared ¶ added in v0.4.2
MakeShared ensures a mounted filesystem has the SHARED mount option enabled. See the supported options in flags.go for further reference.
func MakeSlave ¶ added in v0.4.2
MakeSlave ensures a mounted filesystem has the SLAVE mount option enabled. See the supported options in flags.go for further reference.
func MakeUnbindable ¶ added in v0.4.2
MakeUnbindable ensures a mounted filesystem has the UNBINDABLE mount option enabled. See the supported options in flags.go for further reference.
func Mount ¶
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.
Types ¶
type MountInfo ¶
type MountInfo 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 }
MountInfo reveals information about a particular mounted filesystem. This struct is populated from the content in the /proc/<pid>/mountinfo file.
func PidMountInfo ¶ added in v0.4.2
PidMountInfo collects the mounts for a specific process ID. If the process ID is unknown, it is better to use `GetMounts` which will inspect "/proc/self/mountinfo" instead.
