NAME

       cache_restore - restore cache metadata file to device or file.

SYNOPSIS

       cache_restore [options] -i {xml file} -o {device|file}

DESCRIPTION

       cache_restore  restores  cache  metadata  created  by  the respective device-mapper target
       dumped  into  an  XML  formatted  (see  cache_dump(8))  file,  which  optionally  can   be
       preprocessed  before  the  restore  to  another device or file.  If restored to a metadata
       device, the metadata can be processed by the device-mapper target.

       This tool cannot be run on live metadata.

OPTIONS

       -h, --help
              Print help and exit.

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

       -q, --quiet
              Don't print any output.  Check the exit code to test for success.

       -i, --input {xml file}
              Input xml.

       -o, --output {device|file}
              Output file or device for restored binary metadata.

           If a file is used thin it must be preallocated, and large enough to hold
           the metadata.

       --metadata-version {1|2}
              Choose a metadata version.

DEBUGGING OPTIONS

       --debug-override-metadata-version {integer}
              Override the version stored in the metadata.

       --omit-clean-shutdown
              Don't set the clean shutdown flag.

EXAMPLE

       Restores  the  XML  formatted  cache  metadata  on  file  metadata   to   logical   volume
       /dev/vg/metadata for further processing by the respective device-mapper target:

           $ cache_restore -i metadata -o /dev/vg/metadata

DIAGNOSTICS

       cache_restore returns an exit code of 0 for success or 1 for error.
