     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.

     OPTIONS
          -h, --help
               Print help and exit.

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

          -i, --input {device|file}
               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.

          --transaction-id {natural}
               Override the transaction id given in the input xml.

          --data-block-size {natural}
               Override the data block size given in the input xml.

          --nr-data-blocks {natural}
               Override the nr data blocks given in the input xml.

     EXAMPLE
          Reads the binary thin provisioning metadata from file meta-
          data, repairs it and writes it to logical volume
          /dev/vg/metadata for further processing by the respective
          device-mapper target:

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

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