Comment 19 for bug 581566

GOOD NEWS EVERYONE!

I did it! I mean track it down ... it IS indeed weird and took me 4 hours... :/

Ultrashort FIX (if not boot disk is affected):
- sudo aptitude purge dmraid

YES! It is the f*ke-Raid module, that causes such headache.....is it?
NO! It is the Ubuntu Installer...

Reproduce:
- Start your LIVECD (install or rescue)
- While HD-Setup answer "Enable SATA Raid devices" once with YES and once with NO

1st: This is a very poor option description! - also with 10 years of HW-experience - till now i did not fully understand this option!
Please add some additonal text!
2nd: So - in my case, i was installing WITHOUT this option - everything went fine. And now i did find out, that dmraid is INSTALLED and ENABLED at startup - WHY?!

For dmraid developers:

-- Board: http://www.supermicro.com/products/motherboard/PD/E7230/PDSME.cfm
-- 2x Seagate HD 200GB on sata PORTS
-- FastTrak/Promise SATA-Raid Controller

yes, with ONLY 2 HDs on internal board ports (and empty raid-controller), the partiton nodes are removed if dmraid is enabled...
