era_restore(8) System Manager's Manual era_restore(8)

era_restore - restore era metadata file to device or file.

era_restore [options] -i {xml file} -o {device|file}

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.

Print help and exit.
Print version information and exit.
Don't print any output. Check the exit code to test for success.
Specify input file containing xml metadata.
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.

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

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