I'm wondering if anyone has tried using stride and stripe-width options when creating an ext4 filesystem on a hardware RAID5 array.
Does it improve the performance of the array? Should you create the filesystem directly on the partition? What happens if you create it on a logical volume that is created on the physical partition? The LVM volume was created without options, ie, defaults. I know LVM supports stride and stripes as well but I dont know how they map to a physical RAID device so I've never bothered with it.
