     NAME
          cache_dump - dump cache metadata from device or file to
          standard output.

     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 print-
               ing to stdout.

     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.
