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 formatted 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 writing to stdout.
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.
