nbdkit-split-plugin - nbdkit plugin to concatenate split files into one disk

 nbdkit split [file=]file1 [[file=]file2 [file=]file3 ...]

"nbdkit-split-plugin" is a file plugin for nbdkit(1). One or more filenames may be given using the "FILENAME" parameter. These files are logically concatenated into a single disk image.

If you want to add a virtual partition table, see nbdkit-partitioning-plugin(1).

Normally to serve a single file you should use nbdkit-file-plugin(1). This plugin differs from nbdkit-file-plugin as follows:

  • nbdkit-file-plugin is faster and more efficient. It has a fully parallel implementation, and does not have to deal with the complexity of locating the correct file to serve or splitting requests across files.
  • nbdkit-file-plugin allows you to resize the underlying file dynamically. The underlying files must not be resized when using the split plugin.
  • nbdkit-file-plugin can handle block devices, but the split plugin can only handle plain files.
  • nbdkit-file-plugin handles writes of blocks of zeroes efficiently, but the split plugin cannot.
  • nbdkit-file-plugin can "punch holes" in the backing file in response to a trim request from the client, but the split plugin does not support this.

[file=]FILENAME
One or more files to open. They are logically concatenated in the order they appear on the command line.

This parameter must appear at least once.

"file=" is a magic config key and may be omitted in most cases. See "Magic parameters" in nbdkit(1).

$plugindir/nbdkit-split-plugin.so
The plugin.

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

"nbdkit-split-plugin" first appeared in nbdkit 1.2.

nbdkit(1), nbdkit-plugin(3), nbdkit-file-plugin(1), nbdkit-partitioning-plugin(1).
