thin_restore - Man Page

restore thin provisioning metadata file to device or file.


thin_restore [options] -i {xml file} -o {device|file}


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.


-h,  --help

Print help and exit.

-V,  --version

Print version information and exit.

-q,  --quiet

-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.


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


thin_restore returns an exit code of 0 for success or 1 for error.
