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.
