-Currently Longhorn deployments will only use _one_ disk.  If more are
-specified using the `--num-disks` option, only the first disk will be
-mounted for use by Longhorn.  All other additional disks will remain

+The `--num-disks` option can be used if you want more than one storage disk.
+All storage disks will be made part of a single linear LVM volume mounted for
+use by Longhorn.
