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).
Differences from nbdkit-file-plugin
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.
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).
