The format sub-command in the the kafka-storage.sh tool already supports formatting more than one log directory — by expecting a list of configured log.dirs — and "formatting" only the ones that need so. When multiple log.dirs are configured, a new A new property will be included in meta.properties — directory.id — which will identify each log directory with a UUID. The UUID is randomly generated for each log directory.
meta.properties
When multiple log.dirs are configured, a A new property — — directory.id — will be expected in the meta.properties file in each log directory configured under log.dirs. The property indicates the UUID for the log directory where the file is located.

The kafka-storage.sh tool will be extended to generate this property as described in the previous section.
