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.
