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.

	      Input file or device with metadata.

       -o, --output {device|file}
	      Output file or device.

	      Print help and exit.

       -V, --version
	      Output version information and exit.

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.
