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.
