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.

-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.
