Description of problem:

My workstation has 3 disc setup:

 /dev/md0 /dev/sd{a,b,c}1 RAID 1 -> ext3 (/boot)
 /dev/md1 /dev/sd{a,b,c}2 RAID 5 -> PV -> VG -> LV ext3 ubuntu (/)
                                             -> LV ext3 fedora (/)
                                             -> LV LUKS data

I attempted to install F9 Beta onto the LV "fedora". Anaconda would not
allow this.

I then attempted to create a new LV in the VG (the VG has ~ 50 G unallocated).
Annaconda would not allow this either.

Version-Release number of selected component (if applicable):
9 Beta x86-64

How reproducible:
100%

Steps to Reproduce:
1. Produce disc setup above
2. Boot F9 beta install media
3. Try to either view/edit existing LV or create a new LV
  
Actual results:

Error dialog of:

 "Not enough physical volumes

At least one unused physical volume
partition is needed to create an LVM
volume group"

Expected results:

For it to work.

Additional info:

Whilst Anaconda was able to display the volume group and logical volumes,
the physical volume /dev/md1 was marked with a type of "foreign".

Clicking delete on /dev/md1 gives an error of:

   "Unable to delete

This partition is part of the LVM volume group 'NAME_OF_MY_VOLUME_GROUP'

Anaconda did let me delete the LV "fedora", but I was unable to edit/create
LVs otherwise.
