cache_restore - Man Page

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.
