Manpages - cache_restore.8

*cache_restore *- restore cache metadata file to device or file.

  cache_restore [options] -i {xml file} -o {device|file}

cache_restore restores cache metadata created by the respective device-mapper target dumped into an XML formatted (see cache_dump(8)) file, which optionally can be preprocessed before the restore to another device or file. If restored to a metadata device, the metadata can be processed by the device-mapper target.

This tool cannot be run on live metadata.

-h, –help

Print help and exit.

-V, –version

Print version information and exit.

-q, –quiet

Don’t print any output. Check the exit code to test for success.

-i, –input {xml file}

Input xml.

-o, –output {device|file}

Output file or device for restored binary metadata.

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

–metadata-version {1|2}

Choose a metadata version.

–debug-override-metadata-version {integer}

Override the version stored in the metadata.

–omit-clean-shutdown

Don’t set the clean shutdown flag.

Restores the XML formatted cache metadata on file metadata to logical volume /dev/vg/metadata for further processing by the respective device-mapper target:

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

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