NAME¶
thin_restore - restore thin provisioning metadata file to device or file.
SYNOPSIS¶
thin_restore [options] -i {xml file} -o {device|file}
DESCRIPTION¶
thin_restore restores thin provisioning metadata created by the
respective device-mapper target dumped into an XML formatted (see
thin_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
- Suppress output messages, return only exit code.
- -i, --input {xml file}
- Input file containing XML metadata.
- -o, --output {device|file}
- Output file or device for restored binary metadata.
If a file is used for output, then it must be preallocated, and large
enough to hold the metadata.
EXAMPLE¶
Restores the XML formatted thin provisioning metadata on file metadata to
logical volume /dev/vg/metadata for further processing by the respective
device-mapper target:
$ thin_restore -i metadata -o /dev/vg/metadata
DIAGNOSTICS¶
thin_restore returns an exit code of 0 for success or 1 for error.
