If I use 10-disk RAID5 with 1024 KiB stripe, what would be the correct start and end size if I wanted to make sure the RAID5 was stripe aligned?

Or is there a better way to do this, does parted handle this situation better?

From that setup it seems simple, scrap the partition table and use the
disk device for raid. This is what we do for all data storage disks (hw raid) and sw raid members.
