If your partitioning tool doesn't automatically re-read the
partitioning layout (and it sounds like it didn't in this case), use
hdparm -z /dev/sda to re-read the partitions on sda.  parted usually
re-reads on its own.  And of course after doing the partitioning, and
before using the partitions as raid components, enumerate the drive
partitioning, and verify it is exactly as you expect:

parted /dev/sda print free
