CACHE_DUMP(8)						      System Manager's Manual						     CACHE_DUMP(8)

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 formated metadata can be fed into cache_restore (see cache_restore(8)) in order to put it  back  onto  a
       metadata device (to process by the device-mapper target) or file.

       -r, --repair
       Repair the metadata whilst dumping it.

       -h, --help
       Print help and exit.

       -V, --version
       Output version information and exit.

EXAMPLES

       Dumps the cache metadata on logical volume /dev/vg/metadata to standard output in XML format:

       cache_dump /dev/vg/metadata

EXAMPLES

       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.
