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