NAME

       nbdkit-partition-filter - nbdkit partition filter

SYNOPSIS

        nbdkit --filter=partition plugin partition=PART [plugin-args...]

DESCRIPTION

       "nbdkit-partition-filter" is a filter that limits requests to a single partition within a disk image that
       is served by another plugin.

       Partition numbers are specified by the required "partition" parameter, and count from 1.

       This works like the "qemu-nbd -P" option.

       The opposite of this filter is nbdkit-partitioning-plugin(1) which adds a virtual partition table to a
       file or files.

PARAMETERS

       partition=PART
           The partition number to serve, counting from 1.

           This parameter is required.

EXAMPLE

       disk.img  is  a  partitioned disk image (eg. a virtual machine disk image).  To serve the first partition
       only use:

        nbdkit --filter=partition file disk.img partition=1

FILES

       $filterdir/nbdkit-partition-filter.so
           The filter.

           Use "nbdkit --dump-config" to find the location of $filterdir.

VERSION

       "nbdkit-partition-filter" first appeared in nbdkit 1.2.
