Sometimes the installation finishes, but sometimes it hangs. I had success when trying to install with the default packages three times in a row. I removed the Novell AppArmor and added some development packages to the installation. With this setup it hang during unpacking of one of the BASE packages. I installed using a DVD and typing "install vnc=1 ssh=1" and the command line prompt. The last message I got on the SOL console was: *** Starting YaST2 *** error: cannot open Packages index using db3 - No such file or directory (2) This error message also appeared when the installation was successful. I connected to the ssh server and tailed /var/log/YaST2/y2log (see attachment) The reason for the installer to fail might be related to rpm on nfs: Berkeley DB and NFS don't really go together well at all: http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/remote... =Comment: #2================================================= Jochen Roth - 2008-07-07 06:31 EDT y2log what kernel is on the nfs server? (In reply to comment #6)

...

what kernel is on the nfs server?

It is a pretty old kernel: Linux nfsserver 2.6.5-7.283-pseries64 #1 SMP Wed Nov 29 16:55:53 UTC 2006 ppc64 ppc64 ppc64 GNU/Linux Nfs is AFAIC part of the kernel. Are there any messages displayed on console 10? I'm connected via Serial Over Lan (SOL) to the Blade so I don't have a console 10. But I booted with option ssh=1 and thus I could have a look at some log files. Ok, then could you provide the output of dmesg? I changed the NFS root server: kernel version: 2.6.22.1-41.fc7 on a Fedora 7 JS20 system. The problem still happens. Please find the dmesg output attached. The last line is: lockd: server 10.64.4.131 not responding, still trying But I'm still able to cd to the mounted nfs directory and create files there. This message always occurs even if the installation onto NFS root was successful. ps aux tells me that is in state D ("uninterruptible sleep" usually I/O) root 2846 7.6 3.6 112140 73244 ttyS0 Dl+ 14:23 1:58 y2base installation ("initial") qt --noborder --auto-fonts The WCHAN for this process is "rpc_wait_bit_kill". So it looks like NFS is the root cause for this problem. I'll try to figure out what causes this situation. I just discovered that applying "nolock" as an additional mount option seems to work around this problem.
