thin_restore(8) System Manager's Manual thin_restore(8)

thin_restore - 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.

Print help and exit.
Print version information and exit.
Suppress output messages, return only exit code.
Input file containing XML metadata.
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.
Override the transaction id given in the input xml.
Override the data block size given in the input xml.
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.
