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.
