NAME

       cache_repair - repair cache binary metadata from device/file to device/file.

SYNOPSIS

       cache_repair [options] -i {device|file} -o {device|file}

DESCRIPTION

       cache_repair  reads  binary cache metadata created by the respective device-mapper target from one device
       or file, repairs it and writes it to another 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 containing binary metadata.

       -o, --output {device|file}
              Output file or device for repaired binary metadata.

           If a file is then it must be preallocated, and large enough to hold the
           metadata.

EXAMPLE

       Reads  the  binary  cache  metadata  from  file  metadata,  repairs  it  and  writes it to logical volume
       /dev/vg/metadata for further processing by the respective device-mapper target:

           $ cache_repair -i metadata -o /dev/vg/metadata

DIAGNOSTICS

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