Description of Problem:
The new disk druid seems to have problems deleting unused RAID groups. I
created several sub raid parts on hda and hdb. I put two of them together
as /boot, and tried to delete the third. Disk druid complained that I could
not delete partitions in use.. which this one wasnt yet.
Steps to Reproduce:
1. Install and make 3 subraid partitions
2. Organize 2 into a ext3 partition
3. Delete the unused subraid partition.
Unable to delete RAID partition in use
Should allow for deletion or give better error message as to why not.
This defect considered MUST-FIX for Fairfax gold-release.
I could not reproduce this in beta 2 so our fix appears to work.
