       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  meta-
       data can be processed by the device-mapper target.
       This tool cannot be run on live metadata.

              Print help and exit.
       -V, --version

       -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.
