NAME

       cache_restore - restore cache metadata file to device or file

SYNOPSIS

       cache_restore [options] -i {device|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.

       -i, --input {device|file}
              Input file or device with metadata.

       -o, --output {device|file}
              Output file or device.

       {--debug-override-metadata-version} <integer>
              ONLY FOR DEBUGGING PURPOSES:
              override the version stored in the metadata.

       -h, --help
              Print help and exit.

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

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
