cache_restore(8) System Manager's Manual 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.
