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  postpro‐
       cessing	 in  XML  format.  XML	formated  metadata  can	 be  fed  into
       era_restore (see era_restore(8)) in order to put it back onto  a	 meta‐
       data 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  out‐
       put in XML format:

	   $ era_dump /dev/vg/metadata

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