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.

	      Input file or device with binary metadata.

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