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

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 format‐
       ted  (see  thin_dump(8))  file,  which optionally can be preprocessed before the restore to another device or file. If re‐
       stored 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 pro‐
       cessing 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.
