var ( // ErrUnsupportedFilesystem is an error for unsupported filesystems.

Functions ¶
func DetectFilesystem ¶
DetectFilesystem returns filesystem type if device has a filesystem. This returns an empty string if no filesystem exists.
Types ¶
type Filesystem ¶
type Filesystem interface {
// Exists returns true if the filesystem exists in the underlying block device.
Exists() bool
// Mkfs creates the filesystem on the underlying block device if the filesystem is not yet created.
// This returns ErrFilesystemExists if device has some filesystem.
Mkfs() error
// Mount mounts the filesystem onto the target directory.
// target directory must exist.
// If device is mounted on target, this returns nil.
// If readonly is true, the filesystem will be mounted as read-only.
Mount(target string, readonly bool) error
// Unmount unmounts if device is mounted.
// target directory must exist.
// If not mounted, this does nothing.
Unmount(target string) error
// Resize resizes the filesystem to match the size of the underlying block device.
// It should be called while the filesystem is mounted.
Resize(target string) error
}
Filesystem represents the operations of a filesystem in a block device.
func New ¶
func New(fsType, device string) (Filesystem, error)
New returns a Filesystem if fsType is supported. device must be an existing block device file.
