Anaconda Traceback

Description of problem:
I tried the Fedora 11 Preview Live CD
The installation with anaconda wasn't possible, because it crashed. I included the Traceback.

lspci displays the following RAID controller:
00:1f.2 RAID bus controller: Intel Corporation 82801 SATA RAID Controller (rev 02)

I also couldn't configure the RAID with dmraid:
[root@localhost ~]# dmraid -ay
ERROR: device-mapper target type "raid45" is not in the kernel
RAID set "isw_deaadhfccd_Volume" was not activated

There is actually no module with the name raid45, but I found a raid456.

Is there anything I can do to get the RAID controller working?

Version-Release number of selected component (if applicable):
kernel-2.6.29.1-102.fc11.x86_64
dmraid-1.0.0.rc15-7.fc11.x86_64
anaconda-11.5.0.47-1.x86_64

How reproducible:
Create a RAID 5 with 4 disks on a Gigabyte GA-P35-DS4 mainboard (Intel ICH9R RAID controller)

Expected results:
Anaconda shows one large disk and raid45 is available and loaded as a module

Comment 2 Hans de Goede 2009-05-01 07:51:56 UTC 
This does not work because dmraid45 support is not yet in the upstream kernel,
iow its expected to not work, although I admit the traceback is not pretty.
