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.

-q, --quiet

-i, --input {xml file}
Input file containing XML metadata.
-o, --output {device|file}

    If a file is used for output, then it must be preallocated, and large
