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 pro-
       cessing 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.
