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.
