Yup - if this were a single disk, that would not be a good place to start,
esp. if it was a large disk. I don't know how big the drives in the array
are, and even though parted says it's 512/512 sector size, most new large
drives are, in reality, 4k in hardware/firmware. You *might* consider
repartitioning, but start at 2048k, rather than 1. I suspect that if you
did
parted align-check optimal /dev/sda1
that it would tell you it was not aligned properly.
