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.

EXAMPLE

  Reads the binary thin provisioning metadata from file metadata, 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.
