Thanks for the report. The reason behind this problem is a bit technical: parted and kpartx don't seem to see eye to eye wrt what your partition table looks like.

Can you please do the following, as root in a terminal:
dmsetup table

And paste the output here, then start python:
python

And at the >>> prompt type the following commands:

import parted
dev = parted.Device(path="/dev/mapper/pdc_cabbjieh")
disk = parted.Disk(device=dev)
for p in disk.partitions:
    print p.geometry


You can simply cut and paste the above commands to the python prompt, you need to finish with an empty line, so if the prompt is ... after typing these commands simply press enter.

Now copy and paste the output of these python commands here (as a comment to this bug) too.

Once I have this info I can hopefully figure out what is going on.

Reuben,

Thanks, that is very useful information. This actually is a pyblock issue, so I've changed the component.

I'll attach an updated device.py. Can you please:
1) Boot from the F-13 beta livecd
2) Replace /usr/lib/python2.6/site-packages/block/device.py
   with the attached device.py, note if you're doing a 64 bit install the path
   is /usr/lib64/python2.6/site-packages/block/device.py
3) Start the installer from the livecd desktop and try to install,
   this should work now

Thanks,

Hans

p.s.

Making this an F13Blocker as it breaks installation on any dmraid using BIOS RAID (so not Intel BIOS RAID) system with an extended partition.

Updated pyblock device.py fixing this.

python-pyblock-0.47-1.fc13 has been submitted as an update for Fedora 13.
http://admin.fedoraproject.org/updates/python-pyblock-0.47-1.fc13

Okay, the updated file allowed me to install the beta.

Great, thanks for testing! Could you perhaps give a positive vote to the updated pyblock package with this fix:

Thanks,

Hans

python-pyblock-0.47-1.fc13 has been pushed to the Fedora 13 testing repository.  If problems still persist, please make note of it in this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update python-pyblock'.  You can provide feedback for this update here: http://admin.fedoraproject.org/updates/python-pyblock-0.47-1.fc13

Reuben: thanks for the feedback! Just a note for any future cases: if you have a fedoraproject.org (FAS) account, you can log in to Bodhi with that before leaving your feedback on updates. If you do that, your feedback gets counted in the update's 'score', which can help it get pushed faster. If you could do that for this update it would also be great.

Discussed at today's blocker meeting: we agree this is a blocker, many thanks to Hans for including the rationale in his awesome comments. I will test install works here with the updated python-pyblock package and +1 the update if so.

The updated python-pyblock has been pushed to stable, Reuben confirmed the fix, so closing this.
