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.
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 {xml file} Specify a file for the output rather than writeing to stdout. Examples
Dumps era metadata on logical volume /dev/vg/metadata to standard output in XML format:$ era_dump /dev/vg/metadata
Diagnostics
