Just after the media check the system starts to load the graphical installer, but then crashes with the error:

block.dmraid.GroupingError: .ddf1_disks

see http://homepages.gac.edu/~sommere/rhel5b2installcrash.JPG for a screencap of the stack trace

the system had previously had several raid 1 and 6 arrays. The raid 6 arrays had lvm on top of them.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Set up system with raid devices (both raid 6 and 1) and lvm

3. the installer will crash before you can do anythign about it

Actual Results:

Expected Results:
I should have been able to install over the system

Moving to RHEL 5.5 so it doesn't get mistakenly closed by the bot

Very strange behavior.  And, ofcourse, I can't reproduce :).  I think its directly linked to the setup you have on the box.

Can you please run the following script on tty2.  As soon as you get tty2.

import block
rss = block.getRaidSet()

run it as like this `python scriptName`.  You can also execute it in a python console.  Pls post the output.

Does the system in question actually have BIOS RAID? Or is the raid you mention it has all software raid (mdraid) or full hardware RAID ?

I filed this bug in 2006...

I am almost positive it was mdraid (as the subject of the bug states)

If I remember correctly, I used dd to wipe out the drives and was then able to install.

I _assume_ this has been fixed in the almost 3 years that have past... 

Obviously I can't run a script on the system. I'm not even sure we still HAVE that system, but it has probably been reinstalled a few times since then in any case.

Hmm, you are right, we did leave this one lingering very long, sorry about that.

Ok, closing this as insufficient info then.
