## 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)](https://www.chedong.com/phpMan.php/man/erarestore/8/markdown)) in order to put it back onto a metadata de‐
       vice (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 

## 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.
