era_restore (8) Linux Manual Page
era_restore – restore era metadata file to device or file.
Synopsis
era_restore[options]-i{xml file}-o{device|file}
Description
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.
Example
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.
