I have BZ'd several software raid and LV issues over the months, but 
they get pretty much ignored as not reproducible.  See earlier post this 
list about problems "FC7T4 Not Seeing Pre-existing software raid arrays"
Seems that you must go to console 2 prior to setting up your partitions 
and make sure your raid arrays and LVs are there and active.  Then allow 
anaconda to move to the partitioning phase and use custom configuration. 
  I first noticed problems with raid arrays and LVs during FC6Test days 
and they continue with the change to using the SCSI interface for all 
disk detection and enumeration.
