I am attempting to reuse the partitions on our setup. I have six partitions over two disks. The server is configured like this.
sda1,sdb1 -> raid1 mirror, mounted on /
sda2,sdb2 -> raid1 mirror, mounted as swap
sda3 -> LVM
sdb3 -> LVM
I want to preserve the layout of the disks, and the data on sda3, and sdb3. I don't care about the data on sda1, sdb1, sda2, and sdb2, and I want to reinstall on sda1, sdb1, sda2, and sdb2 given the current layout. I fed Anaconda the following disk configuration hoping to achieve the above.
clearpart --none
partition raid.01 --asprimary --ondisk sda --size 10000 --onpart sda1
partition raid.02 --asprimary --ondisk sdb --size 10000 --onpart sdb1
raid / --level 1 --fsoptions="barrier=1" --device md0 raid.01 raid.02
partition raid.11 --size 512 --ondisk sda --onpart sda2
partition raid.12 --size 512 --ondisk sdb --onpart sdb2
raid swap --level 1 --device md1 raid.11 raid.12
That configuration yields the following back trace.

AttributeError: 'NoneType' object has no attribute 'getActualSize'
I am instrumenting Anaconda now to figure out what is going wrong, but I wanted to post to the newsgroup if someone else knows what I am doing wrong.
This is what I have learned so far.
Step partitionobjinit - All of the disk partitions are properly enumerated. setFromDisk() creates PreexistingPartitionSpecs, and puts them in the correct type.
(My debug messages from getActualSize())
13:30:40 DEBUG : request=Existing Part Request -- mountpoint: None uniqueID: 1
type: software RAID format: None badblocks: None

Step autopartitionexecute - When Anaconda iterates over the raid members it does a lookup by a uniqueID. I can tell from my previous debug messages that those partitions exist for the given unique ID, but when it is executed this time through the partitions are gone?!? Any ideas?
