System Manager's Manual                        Device Mapper Tools                                thin_repair(8)

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.

thin_repair returns an exit code of 0 for success or 1 for error.

       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

-h,--help
              Print help and exit.

              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.
