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



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.


       -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/meta‐
       data 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.
