System Manager's Manual                        Device Mapper Tools                               cache_repair(8)

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.

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

       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
