Synopsis

 nbdkit example3 [size=SIZE]

Example

 nbdkit example3 size=1G
 guestfish --ro --format=raw -a nbd://localhost

Description

nbdkit-example3-plugin is an example nbdkit(1) plugin.

On each connection, it generates a temporary writable block device of size SIZE.  The disk is thrown away when the client disconnects.

The size=SIZE parameter can use a number of common formats to specify the size, eg. 100M, 2G.  If the parameter is omitted, it defaults to 100M.

Mainly this is useful for testing nbdkit and as an example for writing nbdkit plugins (nbdkit-plugin(3)).
