xfs_fsr, sunit, and swidth

[Dave Hall <kdhall@xxxxxxxxxxxxxx>]

Does xfs_fsr react in any way to the sunit and swidth attributes of the 
file system?  In other words, with an XFS filesytem set up directly on a 
hardware RAID, it is recommended that the mount command be changed to 
specify sunit and swidth values that reflect the new geometry of the 
RAID.  In my case, these values were not specified on the mkfs.xfs of a 
rather large file system running on a RAID 6 array.  I am wondering 
adding sunit and swidth parameters to the fstab will cause xfs_fsr to do 
anything different than it is already doing.  Most importantly, will it 
improve performace in any way?

Thanks.

-Dave
