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 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.
