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.

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.
