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 postpro- cessing in XML format. XML formated metadata can be fed into era_re- store (see era_restore(8)) 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 {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 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.
