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.

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.

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.
