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 prepro‐ cessed 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/meta‐ data for further processing by the respective device-mapper target: $ cache_restore -i metadata -o /dev/vg/metadata

DIAGNOSTICS

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