nbdkit-partition-filter - nbdkit partition filter

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

"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.

The partition number to serve, counting from 1.

This parameter is required.

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

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

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

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

nbdkit(1), nbdkit-file-plugin(1), nbdkit-filter(3), nbdkit-offset-filter(1), nbdkit-partitioning-plugin(1), nbdkit-protect-filter(1), nbdkit-truncate-filter(1), parted(8).
