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 postpro- cessing in XML format. XML formated metadata can be fed into era_restore (see era_restore(8)) in order to put it back onto a meta- data 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 youre intending to process the results as it sim- plifies the XML.

EXAMPLES Dumps era metadata on logical volume /dev/vg/metadata to standard out- put in XML format:

era_dump /dev/vg/metadata

DIAGNOSTICS era_dump returns an exit code of 0 for success or 1 for error.
