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 formatted 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 writing 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.
