NAME

6       nbdkit-null-plugin - nbdkit bitbucket plugin
7

SYNOPSIS

9        nbdkit null size=SIZE
10

DESCRIPTION

12       "nbdkit-null-plugin" is a null plugin for nbdkit(1).  Everything
13       written to the virtual device is discarded, and reads back as zeroes.
14
15       Most NBD consumers will be very confused by this device.  Trying to
16       create filesystems etc on it will likely fail badly.  If the client is
17       caching writes locally then you will get inconsistent read behaviour.
18

PARAMETERS

20       size=SIZE
21           Specify the virtual size of the disk image.
22
23           This parameter is required.
