Functions ¶

func CreateFromPath ¶

func CreateFromPath(pathName string, size int64) (backend.Storage, error)

Create a backend.Storage from a path to an image file. Should pass a path to a file /tmp/foo.img The provided file must not exist at the time you call CreateFromPath()

func New ¶

func New(f fs.File, readOnly bool) backend.Storage

Create a backend.Storage from provided fs.File. Will not store any path.

func OpenFromPath ¶

func OpenFromPath(pathName string, readOnly bool) (backend.Storage, error)

Create a backend.Storage from a path to a device Should pass a path to a block device e.g. /dev/sda or a path to a file /tmp/foo.img The provided device/file must exist at the time you call OpenFromPath()

func OpenFromPathWithExclusive ¶ added in v1.9.4

func OpenFromPathWithExclusive(pathName string, readOnly, exclusive bool) (backend.Storage, error)

OpenFromPathWithExclusive is like OpenFromPath but lets the caller choose whether a writable open uses O_EXCL. The exclusive flag is ignored for a read-only open. Callers that shell out to filesystem utilities (e.g. e2fsck/resize2fs) on the child partitions of a whole disk must open the disk non-exclusively: holding the parent disk O_EXCL makes the kernel reject O_EXCL opens of its partitions ("device is in use"). The returned backend records the path, unlike New.
