Yes. sunit/swidth only needs to be added to your fstab if you either got 
the calculation wrong when you initially created the fs and wish to 
correct it, or if you grow the fs later over more drives.

Note that with recent kernels, mkfs.xfs will choose the optimal 
sunit/swidth for you if you are using md RAID or LVM (I believe the 
latter is correct).
