## NAME
       thin_repair - repair thin provisioning binary metadata.

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

## DESCRIPTION
       thin_repair  reads  binary thin provisioning metadata created by the respective device-mapper
       target from one device or file, repairs it and writes it to  different  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.

              Print help and exit.

              Input file or device with binary data.

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

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

## EXAMPLE

       logical volume /dev/vg/metadata for further processing by the respective  device-mapper  tar-
       get:
