CentOS - Apr 2006 - 'partitions not contstrained to drive'???

I was trying to do a new install on RAID1 and my first drive
happened to be partitioned correctly from previous use so
I tried the 'clone partions' option in disk druid to create
matching ones on the second drive and got this error message:

"The source drive has partitions which are not constrained to
the drive /dev/sda".  What does that mean?
