fsextender

README

Extend filesystem to max size with underliing layers. It can extend: ext3, ext4, xfs, LVM Logical volume, LVM Physical volume, LVM Volume Group (with new or free pv) , partitions in MSDOS and GPT partition tables. It can create new partitions and LVM Physical volumes on disk with MSDOS and GPT partition tables.

Расширяет файловую систему до максимального размера, вместе с нижележащими слоями. Может расширять: ext3, ext4, xfs, логические и физические тома LVM, LVM Volume Group (за счет создания новых физических томов и использования уже созданных, но свободных), разделы на дисках с таблицами разделов MSDOS и GPT. Может создавать: новые разделы и физические тома LVM на дисках с таблицами разделов MSDOS и GPT.

Usage example: Пример использования: fsextender [--filter=LVM_ALREADY_PLACED] /home [--do]

Instruction see in usage.txt Инструкцию смотрите в usage.txt

external dependencies: Внешние зависимости:

/proc/mounts - detect mount points /sys/

blkid - detect file system type stat - detect major,minor number of device blockdev - get sector size of disk - need for manipulate with partition tables. partprobe - reread partition table after changes. TODO: replace with blockdev --rereadadpt

Functions

func Asset

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames

func AssetNames() []string

AssetNames returns the names of the assets.

func Main

func Main() int

func MustAsset

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func RestoreAsset

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively
