How to correctly set stripe unit / stripe width of XFS in fstab?

Hi all!

I have a hardware raid controller with a RAID6 volume and an XFS filesystem created directly on it (no partition).
I know there are command line options to specify for mkfs.xfs to properly align to the raid array's stripe size and number of data disks.
However, I am in the process of expanding this array and growing the file system, which means the original parameters are off.
According to several sources I've found you can override the sizes originally used when creating the file system at mount time, by passing the appropriate options in fstab.
What I can't find anywhere however is the correct syntax to do this.

Can anyone help me out with what FSTAB should look like?

Thanks in advance!
