NAME cache_dump - dump cache metadata from device or file to standard output. SYNOPSIS cache_dump [options] {device|file} DESCRIPTION cache_dump dumps binary cache metadata created by the device-mapper cache target on a device or file to standard output for analysis or postprocessing in XML format. XML formatted metadata can be fed into cache_restore 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. -r, --repair Repair the metadata whilst dumping it. -o {xml file} Specify an output file for the xml, rather than printing to stdout. EXAMPLES Dumps the cache metadata on logical volume /dev/vg/metadata to standard output in XML format: $ cache_dump /dev/vg/metadata Dumps the cache metadata on logical volume /dev/vg/metadata whilst repairing it to standard output in XML format: $ cache_dump --repair /dev/vg/metadata DIAGNOSTICS cache_dump returns an exit code of 0 for success or 1 for error.
