chain, use ``"backing": null'' instead.



@subsubsection rbd keyvalue pair encoded filenames: "" (since 3.1.0)



Options for ``rbd'' should be specified according to its runtime options,

like other block drivers.  Legacy parsing of keyvalue pair encoded

filenames is useful to open images with the old format for backing files;

These image files should be updated to use the current format.



Example of legacy encoding:



@code{json:@{"file.driver":"rbd", "file.filename":"rbd:rbd/name"@}}



The above, converted to the current supported format:



@code{json:@{"file.driver":"rbd", "file.pool":"rbd", "file.image":"name"@}}
