You can retrieve the status of your raid by looking at /proc/mdstat. Or you can use ie. mdadm --detail /dev/md0. The md device is built as 2 or more partitions of type software raid, you may view the partition information of the individual parts of your raid by using fdisk on a member drive (you can see which partitions belong to which raid device in /proc/mdstat or by executing mdadm with the option detailed above) ie. fdisk /dev/hda and then type 'p' at the prompt. Changing any of the member partitions of course would screw up your raid.
