     NAME
          cache_repair - repair cache binary metadata from device/file
          to device/file.

     SYNOPSIS
          cache_repair [options] -i {device|file} -o {device|file}

     DESCRIPTION
          cache_repair reads binary cache metadata created by the
          respective device-mapper target from one device or file,
          repairs it and writes it to another device or file. If
          written 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.

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

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

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

     EXAMPLE
          Reads the binary cache metadata from file metadata, repairs
          it and writes it to logical volume /dev/vg/metadata for fur-
          ther processing by the respective device-mapper target:

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

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