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.

DEBUGGING OPTIONS

Override the version stored in the metadata.
- --omit-clean-shutdown

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