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.
- --transaction-id {natural}
- Override the transaction id given in the input xml.
- --data-block-size {natural}
- Override the data block size given in the input xml.
- --nr-data-blocks {natural}
- Override the nr data blocks given in the input xml.
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.
