era_restore8

Usage

Overview

era_restore restores era metadata created by the respective device-mapper target dumped into an XML formatted (see era_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

Don't print any output. Check the exit code to test for success.

-i, --input {xml file}

Specify input file containing xml metadata.

-o, --output {device|file}

Output device or file for restored binary metadata.

    If a file is used, then it must be preallocated, and large enough to hold
    the metadata.

Examples

Restores the XML formatted era metadata on file metadata to logical volume /dev/vg/metadata for further processing by the respective device-mapper target:

    $ era_restore -i metadata -o /dev/vg/metadata

Diagnostics

era_restore returns an exit code of 0 for success or 1 for error.
