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.
