era_dump(8)                 System Manager's Manual                era_dump(8)
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.
