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/meta‐
       data 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.
