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.
