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 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.
