.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`nbdkit\-full\-plugin\*(C'\fR is a plugin for \fBnbdkit\fR\|(1).  Reads from this
virtual disk return zeroes.  All writes and similar operations like
zero and trim fail with \f(CW\*(C`ENOSPC\*(C'\fR (No space left on device) error.
.PP
In other words this behaves like a sparse (thin-provisioned) virtual
disk which has run out of space on the host.
.SS "Equivalent nbdkit-error-filter command"
.IX Subsection "Equivalent nbdkit-error-filter command"
Although this is a standalone plugin, it is equivalent to using
\&\fBnbdkit\-error\-filter\fR\|(1):
.PP
.Vb 4
\& nbdkit \-\-filter=error null SIZE \e
\&                       error\-pwrite=ENOSPC error\-pwrite\-rate=100% \e
\&                       error\-trim=ENOSPC error\-trim\-rate=100% \e
\&                       error\-zero=ENOSPC error\-zero\-rate=100%
.Ve
.PP
nbdkit-error-filter can be more flexible because you can place it on
top of other plugins and you can control when to inject errors.
.SH "PARAMETERS"

Specify the virtual size of the disk image.

\&\f(CW\*(C`size=\*(C'\fR is a magic config key and may be omitted in most cases.
