func (*Client) AttachNFSVolume ¶

func (c *Client) AttachNFSVolume(ctx context.Context, name, mountpoint string,
	publishInfo *models.VolumePublishInfo,
) error

AttachNFSVolume attaches the volume to the local host. This method must be able to accomplish its task using only the data passed in. It may be assumed that this method always runs on the host to which the volume will be attached.

func (*Client) AttachSMBVolume ¶

func (c *Client) AttachSMBVolume(
	ctx context.Context, name, mountpoint, username, password string, publishInfo *models.VolumePublishInfo,
) error

AttachSMBVolume attaches the volume to the local host. This method must be able to accomplish its task using only the data passed in. It may be assumed that this method always runs on the host to which the volume will be attached.

func (*Client) MountFilesystemForResize ¶

func (c *Client) MountFilesystemForResize(
	ctx context.Context, devicePath, stagedTargetPath, mountOptions string,
) (string, error)

MountFilesystemForResize expands a filesystem. The xfs_growfs utility requires a mount point to expand the filesystem. Determining the size of the filesystem requires that the filesystem be mounted.

func (*LinuxClient) ConsistentRead ¶

func (client *LinuxClient) ConsistentRead(filename string, attempts int) ([]byte, error)

ConsistentRead repeatedly reads a file until it gets the same content twice. This is useful when reading files in /proc that are larger than page size and kernel may modify them between individual read() syscalls.

func (*LinuxClient) ConsistentReadMount ¶

func (client *LinuxClient) ConsistentReadMount(ctx context.Context, filename, mountpoint, sourceDevice, devicePath string, maxAttempts int) (*models.MountInfo, error)

ConsistentReadMount verifies whether a specific mountpoint and source device consistently appear in the mount file. It reads the file up to maxAttempts times, returning parsedEntry if the same matching entry is found in two consecutive reads. Returns nil and an error if either the entry was present but not consistently found within the allowed attempts or there was an error. Returns nil and nil if the entry was never found.

func (*LinuxClient) EnsureDirExists ¶

func (client *LinuxClient) EnsureDirExists(ctx context.Context, path string) error

func (*LinuxClient) EnsureFileExists ¶

func (client *LinuxClient) EnsureFileExists(ctx context.Context, path string) error

func (*LinuxClient) GetHostMountInfo ¶

func (client *LinuxClient) GetHostMountInfo(ctx context.Context) ([]models.MountInfo, error)

GetHostMountInfo returns the list of mounts found in /proc/1/mountinfo

func (*LinuxClient) GetSelfMountInfo ¶

func (client *LinuxClient) GetSelfMountInfo(ctx context.Context) ([]models.MountInfo, error)

GetSelfMountInfo returns the list of mounts found in /proc/self/mountinfo

func (*LinuxClient) IsCompatible ¶

func (client *LinuxClient) IsCompatible(ctx context.Context, protocol string) error

IsCompatible checks for compatibility of protocol and platform

func (*LinuxClient) IsLikelyNotMountPoint ¶

func (client *LinuxClient) IsLikelyNotMountPoint(ctx context.Context, mountpoint string) (bool, error)

IsLikelyNotMountPoint uses heuristics to determine if a directory is not a mountpoint. It should return ErrNotExist when the directory does not exist. IsLikelyNotMountPoint does NOT properly detect all mountpoint types most notably Linux bind mounts and symbolic links. For callers that do not care about such situations, this is a faster alternative to scanning the list of mounts. A return value of false means the directory is definitely a mount point. A return value of true means it's not a mount this function knows how to find, but it could still be a mount point.

func (*LinuxClient) IsMounted ¶

func (client *LinuxClient) IsMounted(ctx context.Context, sourceDevice, mountpoint, mountOptions string) (bool, error)

IsMounted verifies if the supplied device is attached at the supplied location. If no source device is specified, any existing mount with the specified mountpoint returns true. If no mountpoint is specified, any existing mount with the specified device returns true.

func (*LinuxClient) IsNFSShareMounted ¶

func (client *LinuxClient) IsNFSShareMounted(ctx context.Context, exportPath, mountpoint string) (bool, error)

func (*LinuxClient) ListMountinfo ¶

func (client *LinuxClient) ListMountinfo(mountFilePath string) ([]models.MountInfo, error)

func (*LinuxClient) ListProcHostMountinfo ¶

func (client *LinuxClient) ListProcHostMountinfo() ([]models.MountInfo, error)

func (*LinuxClient) ListProcMountinfo ¶

func (client *LinuxClient) ListProcMountinfo() ([]models.MountInfo, error)

ListProcMountinfo (Available since Linux 2.6.26) lists information about mount points in the process's mount namespace. Ref: http://man7.org/linux/man-pages/man5/proc.5.html for /proc/[pid]/mountinfo

func (*LinuxClient) ListProcMounts ¶

func (client *LinuxClient) ListProcMounts(mountFilePath string) ([]models.MountPoint, error)

func (*LinuxClient) MountDevice ¶

func (client *LinuxClient) MountDevice(ctx context.Context, device, mountpoint, options string,
	isMountPointFile bool,
) error

MountDevice attaches the supplied device at the supplied location. Use this for iSCSI devices.

func (*LinuxClient) MountNFSPath ¶

func (client *LinuxClient) MountNFSPath(ctx context.Context, exportPath, mountpoint, options string) error

MountNFSPath attaches the supplied NFS share at the supplied location with options.

func (*LinuxClient) MountSMBPath ¶

func (client *LinuxClient) MountSMBPath(ctx context.Context, exportPath, mountpoint, username, password string) error

MountSMBPath is a dummy added for compilation on non-windows platform.

func (*LinuxClient) PVMountpointMappings ¶

func (client *LinuxClient) PVMountpointMappings(ctx context.Context) (map[string]string, error)

PVMountpointMappings identifies devices corresponding to published paths

func (*LinuxClient) PathExists ¶

func (client *LinuxClient) PathExists(path string) bool

func (*LinuxClient) ReadMountProcInfo ¶

RemountDevice remounts the mountpoint with supplied mount options.

func (*LinuxClient) RemoveMountPoint ¶

func (client *LinuxClient) RemoveMountPoint(ctx context.Context, mountPointPath string) error

RemoveMountPoint attempts to unmount and remove the directory of the mountPointPath. This method should be idempotent and safe to call again if it fails the first time.
