       management.

	   Balance chunks across the devices online.

	   Balance and/or convert (change allocation profile of) chunks that
	   passed all filters in a comma-separated list of filters for a
	   particular chunk type. If filter list is not given balance all
	   chunks of that type. In case none of the -d, -m or -s options is

       status [-v] <path>
