Name
cache_restore - restore cache metadata file to device or file.Synopsis
cache_restore [options] -i {xml file} -o {device|file}
Description
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.
Options
-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.
Debugging Options
--debug-override-metadata-version {integer} Override the version stored in the metadata.
--omit-clean-shutdown Don't set the clean shutdown flag.
Example
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
