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

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.
