	  See the xfs man page in section 5 for additional information.



	  This option is mandatory to support zoned block devices. For these

	  devices, the realtime subvolume must be backed by a zoned block

	  device and a regular block device used as the main device (for

	  metadata). If the zoned block device is a host-managed SMR hard-disk

	  containing conventional zones at the beginning of its address space,

	  XFS will use the disk conventional zones as the main device and the

	  remaining sequential write required zones as the backing storage for

	  the realtime subvolume.



	  If unsure, say N.
