thin_restore — restore thin provisioning metadata file to device or file


thin_restore [options] -i {device|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.

-q, --quiet

Suppress output messages, return only exit code.

-i, --input {device|file}

Input file or device with metadata.

-o, --output {device|file}

Output file or device for repaired binary metadata.  If a file is used then it must be preallocated, and large enough to hold the metadata.

-h, --help

Print help and exit.

-V, --version

Output version information and exit.


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.
