NAME
       cache_dump  -  dump cache metadata from device or file to standard out‐
       put.

SYNOPSIS
       cache_dump [options] {device|file}

DESCRIPTION
       cache_dump dumps binary cache metadata  created	by  the	 device-mapper
       cache  target  on  a  device or file to standard output for analysis or
       postprocessing in XML format. XML formatted metadata can	 be  fed  into
       cache_restore  in  order	 to  put  it  back  onto a metadata device (to
       process by the device-mapper target), or file.

       This tool cannot be run on live metadata.

OPTIONS
       -h, --help
	      Print help and exit.

       -V, --version
	      Print version information and exit.

       -r, --repair
	      Repair the metadata whilst dumping it.

       -o {xml file}
	      Specify an output file for the xml, rather than printing to std‐
	      out.

EXAMPLES
       Dumps the cache metadata on logical volume /dev/vg/metadata to standard
       output in XML format:

	   $ cache_dump /dev/vg/metadata

       Dumps the cache metadata	 on  logical  volume  /dev/vg/metadata	whilst
       repairing it to standard output in XML format:

	   $ cache_dump --repair /dev/vg/metadata

DIAGNOSTICS
       cache_dump returns an exit code of 0 for success or 1 for error.
