Description Jochen Roth 2007-05-21 14:28:02 UTC
Description of problem:
The installation of Fedora 7 test4 on multiple multipath SAS disks works fine. 

yaboot tries to boot the installation but fails with the following error message:
0 > boot disk1
Trying to load:  from: /axon@10000000000/plb5/plb4/pcix@4000004600000000/scsi@
2/disk@0,13,f ...   Successfully loaded

aboot.conf: Unknown or corrupt filesystem
Can't open config file
Welcome to yaboot version 1.3.13 (Red Hat 1.3.13-4.fc7)
Enter "help" to get some basic usage information
boot: linux
Please wait, loading kernel...
linux:-1,/vmlinux: Unable to open file, Invalid device

The default partitioning layout for two disks looks like this: 

LVM Group 00 
   -> LogVol01     swap   2GB
   -> SWAP      /  ext3 206GB

   -> ext3    /boot   100MB
   -> LVMGroup0     130GB

   -> PPC PReP Boot    8MB
   -> LVMGroup0      70GB

Version-Release number of selected component (if applicable):
fedora 7 test4 installation DVD

How reproducible:

Steps to Reproduce:
1.Install fedora 7 test4 on 2 SAS disks 
2.Boot installation

Additional info:

This happens on a Cell based system. 

Changing the default partitioning layout to the following solves the problem. 
Note that the PReP and the /boot partition are on the same disk.

LVM Group 00
   -> LogVol01      swap   2GB
   -> LogVol00   /  ext3 206GB

   -> PPC PReP Boot        8MB
   -> /boot       ext3   102MB
   -> VolGroup00         138GB

   -> VolGroup00          68GB

Please attach a compressed tarball of /proc/device-tree

Please also test yaboot 1.3.14rc2 available from yaboot.ozlabs.org built with

Comment 2 Jochen Roth 2007-05-23 08:07:27 UTC
Thanks for the quick reply. 
I created a new installer with the latest yaboot and compiled with DEBUG=1. 

But mysteriously the default partitioning layout is now always correct. 

I suggest to close this bug as unreproducible as the default partitioning layout
is correct now. 

But thanks anyway for your help.
