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

       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:
