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
|
|
|
|
