NAME

nbdkit-random-plugin - plugin to serve random data

SYNOPSIS

 nbdkit random size=SIZE [seed=SEED]

DESCRIPTION

"nbdkit-random-plugin" is a plugin for nbdkit(1) which serves random data, read only.

The size of the virtual disk must be specified using the "size" parameter. If you specify the "seed" parameter then you will get the same random data over multiple runs with the same seed.

The random data is generated using an insecure method (a Linear Congruential Generator). This plugin is mainly good for testing NBD clients.

PARAMETERS

Specify the virtual size of the disk image.

This parameter is required.

Specify the random seed to get repeatable data over multiple runs.

If not specified then a random seed is chosen.
