thin_repair(8)              System Manager's Manual             thin_repair(8)

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 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.
