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.

  -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 further 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.
