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.

       -r, --repair
       Repair the metadata whilst dumping it.

       -h, --help
       Print help and exit.

       -V, --version
       Output version information and exit.

       --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.

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.
