     NAME
          era_dump - dump era metadata from device or file to standard
          output.

     SYNOPSIS
          era_dump [options] {device|file}

     DESCRIPTION
          era_dump dumps binary era metadata created by the device-
          mapper era target on a device or file to standard output for
          analysis or postprocessing in XML format. XML formated
          metadata can be fed into era_restore (see era_restore(8)) 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.

          --repair
               Repair the metadata whilst dumping it.

          --logical
               Fold any unprocessed write sets into the final era
               array.

              You probably want to do this if you're intending to process the results as
              it simplifies the XML.

          -o {xml file} Specify a file for the output rather than
          writeing to stdout.

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

              $ era_dump /dev/vg/metadata

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