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 meta-
       data can be processed by the device-mapper target.

       This tool cannot be run on live metadata.


       -i, --input {device|file}
	      Input file or device with binary metadata.


       -o, --output {device|file}
	      Output  file  or device for repaired binary metadata.  If a file
	      is used then it must be preallocated, and large enough  to  hold
	      the metadata.


       -h, --help
	      Print help and exit.


       -V, --version
	      Output version information and exit.


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.
