NAME

6       nbdkit-partition-filter - nbdkit partition filter
7

SYNOPSIS

9        nbdkit --filter=partition plugin partition=PART [plugin-args...]
10

DESCRIPTION

12       "nbdkit-partition-filter" is a filter that limits requests to a single
13       partition within a disk image that is served by another plugin.
14
15       Partition numbers are specified by the required "partition" parameter,
16       and count from 1.
17
18       This works like the "qemu-nbd -P" option.
19
20       The opposite of this filter is nbdkit-partitioning-plugin(1) which adds
21       a virtual partition table to a file or files.
22

PARAMETERS

24       partition=PART
25           The partition number to serve, counting from 1.
26
27           This parameter is required.
28

EXAMPLE

30       disk.img is a partitioned disk image (eg. a virtual machine disk
31       image).  To serve the first partition only use:
32
33        nbdkit --filter=partition file disk.img partition=1
34

FILES

36       $filterdir/nbdkit-partition-filter.so
37           The filter.
38
39           Use "nbdkit --dump-config" to find the location of $filterdir.
