mkfile(8)

mkfile8

Create a file

Usage

mkfile [-nv] size [{b | k | m | g}] file ...

Overview

mkfile creates one or more files that are suitable for use as NFS-mounted swap areas. The sticky bit is set, and the file is padded with zeroes by default. Non-root users must set the sticky bit using chmod(1). The default size unit is bytes, but the following suffixes may be used to multiply by the given factor: b (512), k (1024), m (1048576), and g (1073741824).

Options

-n

Create an empty filename. The size is noted, but disk blocks aren't allocated until data is written to them.

-v

Verbose. Report the names and sizes of created files.

Warning

If a client's swap file is removed and recreated, it must be re-exported before the client will be able to access it. This action may only be done when the client is not running.
